I am assuming you paid 6% in commissions or 13.2K and 1K to close leaving very little ($467.00)  left for "staging". 

The tenants your trying to contact doesn't sound like they fall in that pool, it's the tenant that say's I understand, I'm sorry, I've worked and found some support and can now figure out how to pay and stay, Will you work with me or is it to late to consider a settlement payment arrangement

She (the investor) is a HNWI who is really relaxed and trusts my partner and we both know that going forward with other investors, this most likely will not be the arrangement.

If he does this, he would like to go ahead and sell once and for all (if possible), but would want to sell as-is and does not want to make payments on a house he no longer lives in while the house is on the market.Therefore, he is open to selling sub2 if his payments are covered, but would prefer some assurance that it wouldn't be an open-ended arrangement.

We also have an additional house in rehab stages we are flipping.

Because I'm actually thinking of partnering but don't know what arrangement to propose that will be in benefit of both of us.

We are in pre-planning stages for a house we found that just came on the market.  

I sold 54 of my homes in Atlanta to a hedge fund for a nice profit but that was in the middle stages of the hedge funds buying sfr's... piece mealing them to investors at or under market is certainly doable.. but remember they are going to want to cash flow positive 200 a door that's what they want and are taught.. you will have inspections and all the rest.. so in my mind discount to market pretty heavy for one buyer.. maybe market smaller discount to market for investor.. and market to may little premium to sub prime owner occ.

Myself, my husband Rafael and our business partner Kyle are wholesalers & rehabbers we currently have 2 wholesale projects under contract and we have 3 rehabs we are beginnings stages of working.

Plus, don't you think it would be respectful of your parents kindness with living arrangements to use this opportunity to propel yourself forward?
