If the IRA is not a Roth, I'd convert it to a Roth, but check with a CPA on how to treat the property in the Roth.

There are many service companies that will manage seller finance notes including the payments, escrow accounts, and documentation. 

@James Galla good point, I’ll check that is morning.

Have a way to double checking their information they give you on the application.  

However, the depreciation claimed while the property was a rental must be accounted for upon the future sale of the personal residence, which could increase your capital gains tax liability.The adjusted basis of the property (original cost minus depreciation) will be used to calculate gains or losses at the time of sale.

Quote from @Jay Hurst: Quote from @Jeremy Torres: Quote from @Patrick Drury: @Jeremy TorresIn terms of what's a good offer you would need to check with an agent or do some research on your own of looking at comps in the market.

I would recommend checking with some local insurance brokers in your area, they may know more carriers that are available."

Credit and background checks, minimum 620 score, income verification, and limit the number of people living in the home.Tenant Own Homes is popular as well, you own the land and collect lot rent!

I do like to check multiple vendors with my originators. 

I would also check out NARPM for a list of local property managers. https://www.narpm.org/about/why-use-a-narpm-memberBest of luck!
