I've wondered if for example it even makes sense on a NNN retail building.Maybe if your CPA can do it cheap as part of their tax return service fee for you.Hopefully just your normal straight line depreciation is the way to go, but check with your CPA and see if they think it is worthwhile for you.   

@Maddison MartinSome market just don't produce cash flow, and the way to profit is through appreciation and tax benefits.

Also (very important) when STR online portals (Airbnb/VRBO etc) will collect tax and send it to your local govt along with the address for which it was collected.

For example, I've recently encountered more potential 203K/renovation loan deals, which has led me to actively seek out HUD Consultant contacts.

A lesson learned in this process so far is that adjusting rent is important specially considering the increases in taxes when going from 4% to 6%.

I recommend you consult with an architect.

Taxes are reappraised every year and if it is not your homestead, your property taxes can go up without limit.You have to really know the market and not just what prices seem to be.

Hello,  if I purchase a rental property in Miami this year and close under my name, and then transfer the title to a LLC the same year, do I need to anticipate TWO times the property tax hike for next year?   

You didn't even mention tenants who don't pay rent, evictions, vacancies, HOA violations, the consistent rise in taxes and insurance, bad property managers, and the many other issues that cut into your profit. 

I need help on how to start a system to buy and sell tax deeds.
