Obviously one would still need legal and accounting support. 

I might also offer them some support such as a dumpster.

There are rules and situations unique to each state and that is why you want to go with a local lender vice someone just reaching out to you telling you they can do it. 2) Better recourse if the lender screws something up: a local lender has more skin in the game so to speak as if they screw something up their name will be mud to local real estate agents in the deal.

That's good for my credit profile and supports a healthy score.

If you’re making a return higher than a bank CD you can support a mortgage.

The ways around that are to build a business around supporting their voucher and inspection program and spending no small amount of effort ensuring they are smoothly servicing your rentals. 

You will also need different levels of staffing to support the various strategies as you are already realizing. 

Support staff at RentRedi were there to answer any questions and help me setup, once setup it runs itself.  

If these folks owned their own home prior, I would probably take that as them having better credit at that time even without a credit report to support it. 

They also want a priority lien on the property.It sounds like you are looking for someone to fund your down payment, I would be looking for an equity partner over debt as nobody likes to lend money in insecure positions, especially when a borrower lacks skin in the game.How much are you planning to come in with yourself?
