Also, I am on a work trip to Menlo Park, CA as I write this.

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.

It should include the following First and last nameEmail addressPhone numbersocial media handlesNotesIn your notes section you will want to write in things like what the potential client is interested in, first and last time you corresponded with them and how you met them.

I ask because most who write similar posts on BiggerPockets are unable and I am sorry but  "A unique blend of benefits that are favorable for R.E investors who are sole proprietors" sounds like something a  fear mongering asset protection company will tell you before upselling the expensive and unnecessary asset protection product.

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

Second: writing off the full cost of a new car is badly overhyped.

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.

This way, if someone feels rejected unfairly, you can show that your decision wasn’t based on any illegal discrimination, but on consistent standards applied to everyone.Alternatively... you could just ghost applicants but that's not always everyone's style lol
