There is no allowable mechanism whereby you draw from the account and repay on a monthly schedule.  

If your not comfortable spraying them yourself, take them to a small Mom and Pop auto body shop and see if they will do them for you.

I told him we would be doing quarterly inspections on all the mechanicals in the house.

Crowdfunding is an exciting new financing mechanism but its still in the early stages of development and, I believe, works best when both the person/company buying the real estate has significant experience and the investors buying in have enough sophistication to understand the terms of what they're getting into.

I have a friend that owns an auto shop/car lot in Westport.

Is so, they usually handle the mechanics. 

Yep, check with your state.In Ohio, you have to be licensed, with a broker, and be a REALTOR to get access to our MLS (plus pay all the dues).If you're just getting your license to get access to the MLS then you're better off creating rapport with a good agent you trust and asking them to set you up on their auto-notification with the criteria of houses you're looking for (On our MLS system, we have that feature to setup clients on auto-notification, so as soon as a house comes on the market that meets their criteria they'll get notified).Also, if you get to know an agent(s), they may know of houses not on the MLS that will be coming on the market, so you could have first access to it.

I'm currently a junior studying mechanical engineering at Binghamton University.

The feedback mechanism will save you grief and ultimately money. 

In our model, we have the approach to take care of the cosmetics, but also just an importantly or more importantly really, are these mechanicals that can be costly into the future.Understanding that a house will always need something well into the future is one thing, but getting an TRUE idea of the useful life remaining is a critical element.
