im new to rental property investment.. we own our home with approx. 65,000 in equity and would like to use some of it to buy our first rental property here in the states ( we have on STR in Dominican Republic).

Now my parents are still married but imagine if you can that one day my father comes home and declares after 40 years of marriage, that he fell in love with his secretary or one of his buddy's at work ( lol, I just had a image of my dad being gay ..) it has happened to 100's of thousands of women.

Rentals can be difficult now in Tampa with the rise in home values and the increase in interest rates (close to 8% now if not already).

Are you targeting single family homes or multi-unit properties. 

We purchased the home on 1/30/2023 for $300,000, invested $20,000 to $30,000 in renovations, and sold it for $465,000 on 5/31/2023.

Purchase price: $177,000 Cash invested: $50,000 - Single-family home in a Residential area near the University of Rochester- Purchased flipped home without inspection, many costly hidden issues revealed after closing - Currently rented for $2,200.

Alternatively, you could also just apply a % annual appreciation based on historic data, but those typically won't give you the most accurate market data since they're averaged out across all/most property classes (e.g. a single family home may appreciate differently in your area than a mobile or multifam property, etc.) 

I would consider the business uses of your home, the basement apartment is considered a rental property if you rent it out.

Property close to an area that a builder will start throwing up homes. 

He's also correct in that the septic systems are rated by the maximum total occupancy of the home (they don't count dens towards that occupancy).
