The reason other markets don’t cash flow is because the values have doubled, triple, or quadrupled in the last 10 years. 

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Verifying last 2 years of rental history very important!

There are couple more but that will take too long to detail. 

We started an LLC last year and are about to file our first return for 2024.

Additionally, while rates aren't historically bad right now, they are higher than 4-5 years ago, and they will be even higher for you as an investor than they were as an owner occupant, which is what you were when you bought originally.I get that you are anxious to add to your portfolio, but that could be achieved without touching your first golden goose.Sometimes on BP, the push is to leverage every last spare penny, but that can be a risky game as the markets shift. 

I realize people are trying to make a living, but anyone who cold calls me is the last person I'd use for any transaction (plus I have people for that!).  

Interesting to see the flip in the last 2 years.

Perhaps the only homes that will last that long are the reinforced concrete structures that David mentioned.
