Buying a Vacation or Second Home in Michigan: What You Need to Know in 2026
Buying a Vacation or Second Home in Michigan: What You Need to Know in 2026
Michigan's lake country continues to pull in buyers looking for a place to escape to — but financing a second home is genuinely different from financing the home you live in, and Michigan adds its own property tax wrinkle most out-of-state (and even in-state) buyers don't see coming. Here's what actually matters before you make an offer. NMLS #137512.
Get Pre-Approved — It's FreeA second home mortgage is not the same product as the loan on your primary residence — the down payment is higher, the rate is a little higher, and the underwriting rules around occupancy and rental use are genuinely stricter. On top of that, Michigan has a property tax rule that catches a lot of vacation home buyers off guard: your cottage or lake house will not qualify for the same tax break your primary residence gets, and the difference is bigger than most people expect.
We've seen a real uptick in second home activity across our Michigan markets recently — buyers who already own a primary residence in Southeast Michigan and are ready to lock down a lake property or a cottage up north. Here's what to know before you get too far into the process.
The Michigan-Specific Tax Trap: No Principal Residence Exemption
This is the single biggest surprise for second home buyers in Michigan, and it has nothing to do with your mortgage — it's a property tax rule. Michigan's Principal Residence Exemption (PRE), sometimes still called the "homestead exemption," exempts your primary residence from up to 18 mills of local school operating tax. A mill equals $1 of tax per $1,000 of taxable value, so on a home with a $200,000 taxable value, that exemption can be worth roughly $3,600 a year.
Vacation homes, seasonal homes, and cottages do not qualify for the PRE — full stop. The state's own exemption affidavit says it directly: these properties "are not occupied as your principal residence and may not be claimed." That means your Michigan lake house or cottage will pay the full local millage rate every year you own it, with no exemption available, regardless of how much time you actually spend there.
What This Actually Looks Like in Dollars
Say you're eyeing a $400,000 lake property with a taxable value of roughly $200,000 (Michigan taxable value typically runs well below market value thanks to Proposal A's assessment caps).
That's not a one-time closing cost — it's every single year you own the property, and it needs to be factored into your monthly carrying cost calculation before you decide what you can comfortably afford.
Snowbirds and Multi-State Owners: Read This Twice
If you already claim a homestead or primary-residence-style property tax exemption on a home in another state — Florida's homestead exemption is the most common example we see — you are not eligible to also claim Michigan's PRE on a Michigan property, even if you genuinely spend significant time there. Michigan's guidelines address this scenario directly: an owner who claims a "substantially similar exemption" in another state has been denied the Michigan PRE in real cases. If you're splitting time between Michigan and a home in Florida, Arizona, or Texas, plan on the Michigan property being taxed as a non-homestead property.
Second Home Financing Rules in 2026
Beyond Michigan's tax rules, the mortgage itself works differently than financing you're used to on a primary residence:
| Requirement | Second Home (2026) |
|---|---|
| Minimum down payment | 10% for well-qualified borrowers (90% max LTV on a purchase) |
| Minimum credit score | Typically 620–680 depending on the lender and pricing tier |
| Maximum DTI | 45%, including both your primary and second home mortgage payments |
| Cash reserves required | 2–6 months of payments, depending on credit and overall file strength |
| Distance from primary residence | No hard mileage rule anymore — underwriters look for genuine vacation/resort characteristics |
| Rental income used to qualify | Not allowed — you must qualify on your own income alone |
| Short-term rental (Airbnb/VRBO) allowed? | Yes, occasionally — as long as you keep exclusive personal-use rights and there's no mandatory rental pool agreement |
| Rate compared to a primary residence | Typically 0.25%–0.50% higher |
One rule worth specifically clearing up: the old "must be 100 miles from your primary residence" guideline that used to define second home eligibility is no longer a hard requirement. Underwriters now look at whether the property genuinely fits a vacation or resort profile — waterfront, a lake community, a seasonal area — rather than applying a strict mileage cutoff. That said, a property that's suspiciously close to your primary residence with no real vacation-market characteristics can still get flagged and reclassified as an investment property, which comes with different, generally stricter terms.
Second Home vs. Investment Property — Know the Difference Before You Apply
This distinction matters more than most buyers realize, because it changes your down payment, your rate, and how you're allowed to qualify:
- Second home: You personally use it for part of the year, it's not subject to a mandatory rental agreement, and you cannot use any rental income to help you qualify. Down payments start around 10%.
- Investment property: Purchased primarily to generate rental income, with a different LTV structure (typically requiring more down) — but rental income from the property can often be used to help you qualify, especially with DSCR loan programs.
- Multi-unit "second homes": If the property has more than one unit, lenders will almost always treat it as an investment property regardless of your intent — Michigan's classic up-north duplex cottage can run into this.
Lake Property Considerations Specific to Michigan
Beyond the tax and financing rules above, Michigan's lake and waterfront market carries a few additional factors worth planning for:
- Well and septic systems are common on lake and rural vacation properties rather than municipal utilities — these can affect both the appraisal process and sometimes require additional lender documentation or inspections.
- Seasonal access matters for some properties, particularly up north — confirm year-round road maintenance and utility access if you plan to use the property outside peak summer months.
- Insurance costs and requirements for waterfront property can run higher than a standard homeowner's policy, and flood zone designation should be confirmed early, since it can affect both your budget and your loan approval timeline.
Why This Matters When You Get Pre-Approved
A generic pre-approval that doesn't account for Michigan's non-homestead tax rate on a second home can significantly understate your real monthly payment — sometimes by several hundred dollars a month once the full 18-mill difference is factored in. We build the realistic, non-homestead property tax estimate into every Michigan second home pre-approval we run, rather than defaulting to a generic county average, so the number you see upfront is the number you'll actually be living with.
Frequently Asked Questions
Can I claim Michigan's Principal Residence Exemption on my vacation home if I spend a lot of time there?
No. The PRE is specifically reserved for a property that is your one true, fixed, and permanent home — the state's own affidavit explicitly excludes vacation homes, seasonal homes, and income property, regardless of how much time you personally spend there. If you already claim a homestead-style exemption on a primary residence elsewhere, including out of state, you cannot also claim it on a Michigan vacation property.
How much more will I pay in property taxes on a Michigan vacation home vs. a primary residence?
The Principal Residence Exemption is worth up to 18 mills — $18 per $1,000 of taxable value — which a non-homestead vacation property does not receive. On a property with a $200,000 taxable value, that's roughly $3,600 more per year than an equivalent primary residence would pay, though the exact figure depends on your specific local millage rate.
Do I need 20% down to buy a second home?
No — conventional second home financing typically starts at 10% down for well-qualified borrowers, not 20%. That said, your rate and mortgage insurance requirements will vary depending on your down payment, credit score, and overall financial profile, so it's worth running your specific numbers rather than assuming a flat percentage.
Can I rent out my Michigan lake house on Airbnb and still finance it as a second home?
Generally yes, as long as you maintain exclusive personal-use rights to the property and it isn't subject to a mandatory rental pool or required rental management agreement. However, you cannot use projected rental income to help you qualify for the loan on a second home — that's only allowed for properties financed as investment properties.
Does my second home need to be a certain distance from my primary residence?
Not anymore — the old 100-mile guideline is no longer a hard rule. Today, underwriters evaluate whether the property genuinely fits a vacation, resort, or seasonal profile rather than applying a strict mileage cutoff. That said, a property very close to your primary residence with no clear vacation-market characteristics may still raise questions and get reviewed more closely.
