I know I need to calm down but I am angry at my realtor because she didn't get CDL or SSN card or credit report, (the tenant provided the credit report), and I am angry at myself. 

(Should I buy a foreclosed property, leverage my "first-time-home-buyer-card" and use it as a 5ish% downpayment on a townhome in the 200-300s, or save it in a high-yield savings account until I have another 10k?)

Some of your questions are state specific (taxes are charged and paid differently in every state, so I can't address that).

If you're the only one charging for gas on top of the rent, then I wouldn't consider it.Unlike water, and if you control the thermostat as I do at my rentals, unless the tenants purposely leave the windows open on cold days to spite you, you do have some control over gas usage.

Yes, he can charge it because you agreed to it.3.

I'd call a few roofers in the area off of Craigslist and ask them, in general, what they'd charge per square for a basic, asphalt shingle roof.

A couple of days ago he said he would retrieve it yesterday and still has not taken it.Please advise me of what I can do:  can i charge storage fee (how much/day)?

If a tenant sees me as more of a friend, then it makes it more difficult to charge late fees, charge them for damages, etc. 

My first questions would be what the felony charges were for. 

So, how much more should I be charging to make it worthwhile?
