Here's another book I would recommend: Building Wealth One House at a Time, Updated and Expanded, Second Edition - by: John W.

Also I read someone saying to get professional photos, another option is when you retake them have someone on Fiverr edit them. 

Be prepared for the nicer the town the lower the cash flow. edit:--and by stale I mean a buyers market (which isnt the case for most of the northeast)

Written by attorney investors, it's full of practical advice pertaining to management of investment property, has sample forms that can be edited, and - most importantly - they tell you what your primary state laws are and where you can read them.

*EDIT* Adding some keywords to make sure folks see this - Philadelphia, Delaware County, PA, Pennsylvania, wholesale

[EDIT: This post was meant for a different thread.

But my goal is to start with a rough draft and then have the lawyer edit it to create the final copy. 

(Thanks, Business Law with UCC applications, 13th Edition ;)) I think this portion of the law is what you're most concerned with as I'm of the opinion that your contract offers consideration (a house for money), you're legally permitted to assume that the other party to the contract possesses the capacity required, and I'm just assuming that there is nothing illegal about the exchange.Assuming your offer was in writing (real property contracts require writing), and you appointed your agent in writing, and your agent made the offer on your behalf (or you made the offer directly in writing), AND your contract spelled out clear and reasonably definite terms, AND it was signed, witnessed, and delivered, I would say you've got pretty good grounds to pursue the contract. 

My next purchase will be a much larger one than I have ever done in the past, and something that will involve more moving parts, so I would get an attorney to review everything with minor edits, or for a large enough deal just have it drafted from scratch.

Edited: BP wouldn't allow me to post his contact info.
