This would help you get going.You might be able to make these a  little nicer and force appreciation and a little higher rent.Either way rents will go up over time and the mortgage with remain constant.Maybe even make one unit a STR which could see higher income.I'd be ok with break even or a little bit negative on a Quad given you have 4 properties in one.If you're only breaking even you still have depreciation and other tax write off to help you out.I usually make people 3 offers.

Can I still write those expenses on my Schedule C?

I don't know your area, so I can only write to my experiences in PA.You don't really convert your property to Section 8 (S8), but rather sign a lease with a tenant who happens to be funded by S8.

I don't like AI descriptions (sorry @Andrew Steffens).They look and sound completely like it was written by a bot, which it was.I like to write my own copy for listings and I respond directly to all guests, inquiries and issues.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

I require proof of income, and verify it by contacting the human resources department of their employer in writing. 

I am writing this because I appreciated the call and while I have no affiliation with them or have experience working with this company nor have I invested with them - they answered the phone immediately.
