If you are unsure, to start, hire a property manager and don't let the tenants know you are the owner. 

Quote from @Geoffrey Paugam: I suspect there are many managers there, but maybe not any good ones?

He get's principal and simple interest payments over a number of years.I'll manage the deal and the property.Looking to create a proforma for this that would fit a typical rental analysis but insert the detail of having private money cover the DP.

A bonus is if that company also manages and will stand behind that property after the sale to an investor like you.if you have the time, desire, risk tolerance, and knowledge, you can absolutely find and or create deals on your own.  

I currently work with investors who are looking to invest SFH/LTR that are turn-key ready and manage for them on the back end, so I see a lot of benefits in that market across the board. 

What worked for me was focusing on building strategic relationships with top tier people (quality partners) who could complement what I brought to the table—sales, management, and execution.When you are approaching sellers for creative financing, leading with a clear value proposition (and CONFIDENTLY) is key.

Hey Barbara, I have a property manager I can recommend for the LAIC service.

You should consult with local property managers and find what the average DOM would be to lease your home and rental rates etc. this would be a good starting point. 

It's best to have a house manager.

Property managers can be great sources for deals.3.
