I've been using Forewarn lately to verify buyers/sellers and it has worked great for me (free for Realtors at least in my area, $20/month otherwise I believe). 

My first rental tentent (none section 8) from the start never paid their rent ontime...and after 4 months I ended up getting them evicted.

If you know anything about building in Philly the plans and permits can be the hardest part of the project with it often taking many months to get everything in place just to be able to start construction.

The credit bureaus report your score once per month, not every day.

Pro-rated first month's rent would be due at move in. 

If I need to undergo a colonoscopy to determine if a lender makes a 30 year loan to people with an 815 FICO at 85% LTV with an in place tenant and monthly income of $1400 with a market value of $125,000, or if you can't tell me any interest rate info until I submit my tax returns to you...

This can be done within the first six months after the initial cash purchase.

You don't need to know everything to get started; you need a foundation to build on and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

They would pay all utilities and maintenance on the property and provide 2 months security deposit.
