While that number looks very close to the projected returns from the inventory spreadsheets, once you get to year 2 and beyond, you don't get reimbursed for the tenant sourcing fees.

Recently I have offered to reimburse an accepted tenant their Locators fee, at the end of an initial lease period, but did not do so back when I actually accepted one of their prospects.

As long as you properly account for the expenses and get reimbursed by the company it should be OK. 

You would not be able to reimburse any expenses, costs or losses, and you would not be able to guarantee or indemnify the temporary buyer/owner for/from anything. 

Even with the help of friends, you would still have to reimburse for their time and expenses IMO, so you would not be savings 7-10% of the property incoming rent.

If I was local I would handle it myself and reimburse the wholesaler for lockbox.

You put your funds upfront and reimburse with 90 days ( est ).

Also, ask for full reimbursement of the applicable charges.  

You could end up reimbursing the tenant for every penny he has paid you.

OR . . . you can work with a hard money lender that has been through all of that, knows what they are doing, and could use your funds to reimburse their loan money disbursed, and see if they will part with their performing mortgage notes.
