I guess we can do a walk through and discuss the price in advance, what are the rules of thumb for figuring out a fair price for repairs, cleaning, maintenance etc. ? 

do you know and understand the CA ADU rules.  

I started compiling a list of private lenders by going to the county recorder's office, looking at the 1st page of the deeds of trust that were recorded, and writing down the name and address of anything that appeared to be a non-bank in the section "When recorded, mail to:" It was tedious and took me about 4 hours to compile 50 names.

Most Banks only offer a 50% rental offset and a cap of 5 rental properties...

would you take $100/door if you also made a 50% increase in equity?

Not an advocate of big gov, just do their jobs efficiently and enforce the rules evenly.     

We lived in HOA and needed to pay several hundred to send out hoa disclosure package send a certification to buyer that property was in line with all hoa rules, another expense I forgot about. 

I plan on doing the following: 1.PM will pay 50% of standard rent but will identify duties he has to do for 50%. 2.Develop Property Manager Agreement for emergency and routine repairs and come to terms on compensation.

In regard to the $900 price, it sounds reasonable if you had 50 units - maybe, I don't know.... if you cant afford the time then its a cost you have to include. 

., we do the renovations and once the property is sold the profit would be split 50-50.
