Most banks hire 3rd party asset management companies handle the sale, so if you call the bank they will just pass you off - that will be after being tossed around from department to department for two hours. 

If you want more specific numbers, it's best to get real estimates from your lender, title, insurance companies.

Finding the cleaner/cleaning company is the hardest part.

I am having a mudjacking company jack up some concrete that is sloping towards the property, possibly causing most of the dampness issues.

Do you have a company you recommend for SDIRA's? 

I use these:LEPOWER LED Security Lights Motion Sensor Light Outdoor, 38W 4200LM Light, 5500K, IP65 Waterproof, 3 Head Detected Flood for Garage, Yard, Porch (White) - Amazon.comWhen flipping out of state I go Simpli Safe.When it comes to local flips I have a home security contracting company that has their own alarm system and app that I really like so I use them but they are local to Cleveland. 

Does anybody have a recommendation for a Solo 401k compliance company?

I'm not sure about where you would find internships but maybe you could work as an assistant at a real estate brokerage, a real estate investment, property management, or inspection company.  

For my small size it seemed unnecessary and I didn't see the benefit in the small companies for a small time guy like myself.What I do is I can collect rent through Venmo (free), I have a tennant application embedded into my website (cognito forms...also free) I screen tennants through mysmartmove.com (Transunion's company gives you credit report, background, criminal, eviction etc. and tennant pays for the screening so also free.) 

I always do my transactions through a third party title and escrow company or real estate attorney.
