Your best bet area wise is the Shenendoah/coral bluff areas between coral gables and brickell.

Poorly done garage conversions are an eyesore for sure.

Best bet here is to find someone who's a bit new to the game and hungry since they'll be calling owners 24/7.

.- I was able to get approved for access to private investigator software to find the true owners of these properties since conventional skiptracing produced poor results.

@Elliot Tan finding an attorney to answer these questions will probably be your best bet.

Your best bet is to network and reach out to many new investors in the area and ask for referrals. 

Based on the market and the improvements I would bet the property has increased significantly in value. 

A few key highlights are:-A key indicator to determine the best cities to invest in and where to expect the most growth is the recovery of the business services jobs, (services related to operating a business like accountants, lawyers, cleaning jobs, IT)- The faster jobs in business services pick up, the more likely a market will be a good long-term bet for real estate investors-San Antonio made the list for one of the top cities for business services job growth!

Therefore, markets with higher appreciation expectations typically start with poor cash flow (think coastal So Cal, NYC, etc.).  

I think your best bet will be to shop, shop, shop and see if you can find someone who has an opening.
