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.

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

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. 

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.

I have State farms on my main house & attached ADU, but since they are NOT issuing new policies in California, I have been unable to find an INS company willing to just provide INS for my rental.
