He is a licensed contractor with good reviews and referrals.The Owens Corning Platinum Roofing Contractor proposed $17.5k for the whole roof replacement with Owens Corning Duration material, 10 yr transferrable workmanship warranty, and transferrable Platinum protection limited warranty ( Lifetime of workmanship warranty with coverage reduced after 25 years based on the age of the roof).From an investor standpoint, what would add more value to the property?

Conforming loan limits increased to $647,200 for most of the U.S., which means you may be able to avoid the stricter requirements of a jumbo loan.

My long term exposure is $0 as any potential loss is limited to $1. 

I have a pretty decent list as well, but I don't have anything south of Loveland so it would probably be of limited value to you.

Yes, you live in a rent controlled apartment.....and when you argue for your limitations, you get to keep them my man.

The issue we’re running into is that inventory on the MLS is limited, and we’re not sure how to find an owner who is willing to sell.

Then look honestly at money on hand like the income from the airbnb, your next paycheck, savings, credit card limits, etc. 

I invested $25k into a 312 unit apartment complex as a limited partner last year, and I would never claim that I own 312 units.

With the very limited info I have, I would say you are looking at a starting price of $55/ft not including any water proofing.

@Yuzi Stha why would you put that limitation in your lease if you aren’t going to stick to it?
