Larger firms (think American Homes 4 Rent, etc..)While I've looked for a source online to break down the market, I've been unsuccessful. 

It would be easier to have a larger park with more income..If your thinking about it make sure you have the proper reserves or insurance.. and make sure you dont cheap on your due diligence on evaluating the well and septics and know the replacement costs including replacing the pumps.. and how frequent the well needs to be monitored to abide by EPA standards.. 

Try talking to the smaller lenders and see if they offer flexibility that the larger ones do not.

Then there are larger investments such as syndications larger multifamily projects.  

Make sure they are underwritten by a larger title company.

If they invest cash too, it gets you more properties, so the split can be covered by larger volume.

I am looking at a 2.2 million complex and with only capital of half the down payment for 20%, curious if there are loan products to bridge the gap or make a larger purchase more realistic (minus getting additional funding).Thank you!

It was a larger project than anticipated.

It sucks your energy, time and it will absolutely drain your bank account. 

You did not get them into the predicament they are in and buying their house is a solution to their problem, but if you don't start nudging them to go (more than asking a realtor to find them a rental), they will never, ever leave and you will have wasted time and energy on a project here that fails when you could have already closed a different deal and been in renovation.
