When you open escrow you deposit a financial or written instrument, such as a deed, with a neutral third party (the Escrow agent), under an agreement of two parties to a valid contract.

Maybe you could get their number somewhere and try to validate the real owner.

You put gas, oil, spare parts and labor into it, and in 10 years its worth nearly nothing.

Talk to an attorney and they'll tell you that a signed offer with a purchase price is valid without earnest money.2.

I've not read the book, but jumping from 100 to 200 isn't going to be statistically valid as a population for analysis, that is too far apart in any market.I suggest you concentrate on the goals at hand, learning the basics, local methods and markets and getting past that examination.

My advise to you would be Market yourself, Market yourself, Market yourself never take the foot off the marketing gas pedal 

@Gabe Gordon nearly everyone has advised you against just leasing to her when you already have a valid lease.
