I have a degree in Building Construction from the University of North FL and I currently work for a construction firm as a Project Manager in West Palm Beach FL.

I feel like generally this gives you a slightly better tenant pool then other Section 8 programs, but you milage may vary. 

Title Insurance is a MUST, before finalization.Lien enforcement varies by city and county, in Florida.

With teams, however, quality of work may vary, depending upon which team member does your work that day.

Cost can vary as you have lender fees and broker fees.

Roofing varies around the country but in my area it goes for about $3.70/SQFT.

And I am sure there are many varied opinions… I keep enough where “I feel comfortable”… And honestly, sometimes that wasn’t enough!

An interest rate on a line of credit will vary depending on your credit…Yes, you can go for a while doing this… But many lenders will quit lending to you after you have so many mortgages… Many lenders will quit loaning to someone once they have 10 mortgages.And lastly… It is best to fully understand lenders guidelines before starting something like this… Talk to some mortgage people to make sure you are able to get done what you are trying to do…
