Find 2 handymen, 2 electricians, 2 HVAC, and 2 plumbers that you can call on for repairs if needed.

They were the result of the years of networking, building a reputation, having access to capital, and developing a great reputation/track record of honesty, fair play and success that brought me the deal flow those deals were part of.  

Sometimes, other trades like plumbers remove structure in ways that are not appropriate.

If you don't want to hire a P.M then get a team in place... handyman, electrician, plumber, hvac, locksmith and whoever else you need.

sometimes my licensed plumber has two offering : with unpermitted 5k with permit 10k, technically it is the same job by the same subcons….and he said if city ask permit later on , I will bill you 3 k later , so there are these model as well.

He also told me that I could use his team of plumbers, electricians, flooring guys, etc if I ever needed help with any of that.....and so I did. 

I have an excellent PM company and reputable turnkey operator in Memphis that I can refer you to. 

OTH, I think most of the seller financing issues are consumer driven, the banks never did have a slice of that market nor would or could they, and still can't.An HML type needs to be aware of such issues as they will be working closely with banks and will want a good reputation and working with the public, they had better keep fairness in mind as well.

They are very reputable. 

Gen Z may be leading a revival in the trades. 1) In an aging population, the median age of electricians, mechanics, and plumbers is falling. 2) Vocational school enrollment is growing faster than at 4-year colleges.More young folks are considering the trades as a career.
