Are there lenders that will finance something like this or all or owner financing.

You can exchange into one or more properties if you select the 3 property method.So you could close on 2 of 3 selections and split out the 1031 funds to diversify but it is harder to do then completing 1 exchange out of the 3 selected.Once you 1031 if you take out a loan on that property with a refi you can cash back out some or all of that money depending on the loan to value of the replacement property you bought.

I'm currently very familiar with Zoho and know I can put it to good use but reluctant as it is not a "real estate-focused platform" or all-in-one platform.

Is this on the REO side, short sale side, bank side or all sides?

If they were and the house was in good shape they would get most or all of their deposit back.

Even if you can find private financing for some or all of the down payment you still need to have the credit support for the loan.
