This will give you a huge leg up on the competition.

Make sure you do a proper competitive market analysis.

Your competition will consist of fix and flip investors, buy and hold investors, and owner occupants such as yourself.

Be that as it may, Miami itself packs on significantly more than characteristic excellence, with an unimaginably vibrant art and music scene, and world-class sports groups.

Agent's are not actively trying to sell the home and provide feedback on how to make it more competitive.

Seriously,you need to find a local contractor or building inspector to show you all of the actual problems that need repairs.If the plumbing and electrical haven't been upgraded in 100 years,change it all out immediately before they fail in the middle of winter.Make sure your HVAC is excellent as well.That roof probably needs tending to as well.Then you need repainting,spray foam insulation,flooring,etc.What fixtures is your competition for renters using in their homes?

Short-term rental market- 10 years ago was less competition, now more and more people are renting short term and lots of advertising sites for vacation rentals.

Also, tertiary markets that aren't as highly competitive often offer better deals.Even with cap rates currently compressed, rents locally are going nowhere but up.  

@Joshua Howaniec I agree with Claire, however, the response rate of 8-9% on yellow letters is likely in lower competitive markets.  

Then, with limited time, check for IRS liens and have your title rep  pull up liens for each property and correlate results.I do not like auctions because they promote competition!
