The numbers are tough and it's hard to account for all unforseen expenses.

Not calculating maintenance expense could end up being a nightmare.I always estimate (using either the 50%, 1% or square footage rule) the annual maintenance / first year of maintenance fees for a ALL rental property.

Once that reserve fund is established, move all future cash flow to an investment account.

Everyone that has more than 1 or 2 properties should have some kind of basic spreadsheet that demonstrates how much that property is bringing in after all your fixed costs are accounted for, at a minimum - PITI, lawn care, HOA fees, etc.

I created an account and listing on Furnished Finder but not getting many leads.

If your rate is lower than what you can get by investing, taking account for risk, then pay the minimum.

If there were a bulk subscription I could get all my tenants for a low annual or monthly cost I would consider it though

Make sure you are taking into account closing costs as well as the repair money!

I opened a business checking account with Regions.

I would also be sure to sweep the chimney and have it inspected before you rent it out then annually.
