All the housing agencies send their voucher holders there.Just be forewarned - many S8 voucher holders don't want to pay application fees, provide any documentation, expect you to fill out their S8 paperwork (!)

@Rick Albert Can Oakland Landlords Inquire into Criminal Records on Applications?

(free application fee, move in gift, etc.)There are lots of great ways to promote your rental. 

Open a new application with an actual lender that isn't going to charge 12k in origination fees. 4.5% origination on this deal is insane, the broker / lender are ripping you.If you take this to another lender as is (not great credit, no experience, light rehab amount) you would likely get denied again. 

How much of that income will the mortgage companies allow you to use as income on the loan application?  

According to Experian "78% of U.S. consumers' FICO® Scores are higher than 620." 620 is objectively a very bad credit score with a high probability of delinquency.For my rentals, 700 is the minimum and any applicant with lower credit score will need someone else to serve as a personal guarantor.

Consider the cost of the property, mortgage payments, property taxes, insurance, maintenance, and property management fees (if applicable).

Just trying to get some overall opinion on online sites for applications and background checks vs going old school and having them hand fill out applications.

@John Warren Some I do post on MLS, but I like to meet all applicants before recomending them if possible and I would rather keep all the commision. lol.

Hard to say right off the bat which is a better option since it depends a lot on what you are looking for and your situation but speaking with a lender that understands the application of primary residence loans in multifamily will be important to help you find the right option.
