The current area we are living in is very expensive (Boerne, TX) and is a heavily deed restricted region.

Purchase price: $150,000 Cash invested: $100,000 Recently completed a purchase and renovation of a multi-family house in Cleveland Heights, Ohio (BRRRR Method).

What a great town.Check out - https://www.cityhs.net/1265/Short-term-Rental-InformationShould have some rules and regs for you to peruse.I will say that lakefront is often restricted or banned for STRs there.

My main concern is that someone  told me that there are HOAs whose rules are so restrictive that people who bought lots found they couldn't even build.

You want a ratio of 1 to 1, anything higher is more restrictive and can mean you will get less money then you are after. 3.

Because two thirds of the buyers are Mexicans, who were much less affected by travel and other restrictions.

I verified with the city and investors can add them with meters on single-family homes as long as there are no deed restrictions.

Also depending on if you want to stay in Clearwater or not there are also some local restrictions on STR.

As the property is a SFH (Single Family Home) it is exempt from the most restrictive rent control measures in place. 

I wouldn't buy one from scratch if you don't have the experience. especially in miami where it's one of the most expensive places for land in the country. the areas you are talking about can exceed more than 20 million an acre depending on height allowances
