I have a few people in mind who I would like to ask to be a mentor, but I want to find a way to bring them value in exchange for their time and energy.

I inspect my own properties once a year, I try to take care of the things that reduce later damage like cleaning the gutters and servicing the furnaces.

Same with the hit on sales price, they don't want their buyer going down some wonky loan rabbit hole over a $1000 roof leak, that's going to reduce the sales price they can get by a LOT more than $1k.

That place is an energy pig, that I can promise you.All that being said, a $650k property that gets $6600/month in rental income could be a solid deal. 

Oil and gas, and lately solar and wind energy are huge right now.

After reviewing the supporting docs, the amount was reduced to $220,000 due to the type of employment of one of the borrowers. 

.- Chicago: Heat/Energy Disclosure Statement (only if tenants pay their own heat, tenant to sign)- Chicago: Chicago Recycling Ordinance Flyer/Disclosure (tenant to sign)- Illinois: "Protect Your Family From Lead In Your Home" guide. 

Right now any energy not going towards finding a deal is wasted.

Trying to prove this new person lives there isn’t worth your time or energy and my guess is the new roommate has lived there since the beginning.  

Sending you positive energy and with what you have mentioned so far, you will have great success with your goals.
