Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620, many blemishes, but should have no evictions in last 2 years.

Which payment do you think would be easier to cover with rent? 

If they want to be in early, they should start paying early and have a signed agreement covering that time period.

The cash flow from the other units may or may not cover your expenses or mortgage, but that's not the end of the world. 2-4 units in FL are expensive right now, but it allows you to get your own place, pay down the principal and start building your track record and portfolio. 

It looks like most of it was painted over and/or given a cosmetic "covering".

It didn't work because the TV covered a 13 county area and most leads were out of my target area.

By renting out one unit, I covered a significant portion of my mortgage, reducing my monthly housing expenses and easing financial pressure.2.

Some people see it as a way to get into a multifamily house at a lower downpayment and interest rate, while still providing themselves a place to live.I think the only way it would be "wrong" is if it puts you in a situation you can't afford or makes you "house poor".My husband and I rent out 4 of the bedrooms in our house plus a bonus room, meaning we have 6 roommates, but our entire mortgage is covered.

Obviously make sure that potential rents cover the majority, if not all, of the mortgage payment and other expenses.

So maybe cover that In your agreement as well.
