Is it feasible - in Miami, Fl - to look for a property of 500k, put 20% down and expect 20% return after expenses including mortgage?

Due to the seller living several hours away in Canada closing in the same location is not really feasible.

Making a feasibility study sheet has been very educational as so many questions are raised .

But since then, I've scaled up my marketing to 5k-10k letters so it's not feasible anymore.

Most average cities don't know what the hell they are doing or saying because they don't see ADUs except for 5x a year and simply deny them.My tour and research of a company called US Modular in California has the GC getting the feasibility study done for $3500 (used as a credit towards the build but is a fee if you don't move forward with build). 

This is what inspection, feasibility, and other clauses are for.

(a) the gravity of the harmoutweighs the utility of the conduct or(b) the harm caused is serious and the cost tocompensate for it makes the conduct not feasible).

Okay, to start, what are the best neighborhoods for cash flow where it's feasible to enter the market without putting a lot down.

@Rick Albert you make a good point about the feasibility of a 3rd unit.

I have some great market feasibility study proposals that yield high internal rate of returns.
