I have attempted to contact the seller and they are motivated, I am trying to meet them to schedule.  

I would attempt to raise the rate to see if someone will bite.

I am attempting to rent out my home of 12 years now .

A word of GREAT caution attempting to self-repair your credit... 

I am new to REI and am attempting to explore all avenues to make my first deal.

I “thought” they would come back and get the second in the next few days.Unfortunately four weeks went by and despite certified letters and phone calls to the previous owners from the realtor, it was never removed.Ultimately I paid a guy $275 to make it disappear.Obviously, I have not been happy having to deal with this problem for the last month and the fact that I had to pay for its removal is maddening.Especially since I feel that both realty companies, the previous owner and the contractor all walked away with my money and I was left holding this bag.In the future I will not make this mistake.But, my question to BP is whom should I attempt to get reimbursed?

If you're adventuring into an alternative in the attempts to make it mainstream, I'd give these a thought and make sure your payback is in line with the  long term desirability .

As a wholesaler, would you wait and attempt to contract with the seller at a later date or would you just ditch this house and keep going?

Either they are a fool or you are, or perhaps both, but not neither.I won't even begin to get into the gaping flaws in your logic about valuation ... that shows either ignorance on real estate valuation or an attempt to artificially pump up values using valuation methods that are not valid.

Attempts to negotiate a higher rent is hopeless.
