Its a limited doc program  my suggestion is to close the land cash and refinance into multiple loan options and negotiate with at least 5 lenders and talk about terms. you may not even be qualified.

A more financially stable, long term investor can see the long term appreciation play without the need for the cash-flow.  

However, do you have an existing loan/mortgage on the property? 

With the landscape of today's interest rates how would you go about marketing a property for sale that has an assumable loans?

Also, does/can this work with only raising part of the money via private money and the rest via a DSCR loan?  

Look into a hard money loan so you can get the rehab budget covered, and make sure the rehab budget is non-dutch so you do not pay interest on the rehab budget until you begin to make reimbursement draws.

All VA, FHA and USDA loans are assumable and even a few Conventional loan products out there are assumable as well.

You either reimburse everyone or reimburse nobody and then you are in compliance with fair housing.Unless you rented a furnished apartment, I don't see how you could be responsible for wall anchors, either financially or for liability.  

It depends on the type of loan you are applying for.

A portion of the payment is going towards loan pay down.
