Joe, I've replaced five roofs in Mississippi and the most expensive one was 10K and that house was over 2200 square feet.

Build a strong credit score by responsible usage of credit cards, reading books, and engaging in forums.

I also got a business credit card for buying things related to the rentals. 

I’ve been in the real estate business for almost three years now and have completed five deals: one buy-and-hold long-term rental, one short-term rental, and three fix-and-flip projects, for which I helped raise capital.
