Are you not necessarily denying him based on screening criteria - Some landlords make it a requirement to view the property prior to letting the applicant apply.

District Office Permit Application.15.

Hello,I am in Seattle area and I have a student applicant who is using a his mom as a co-signer.

Assets identified in this study include:Standard windows and doorsInterior ceilings and wallsBasic plumbing and electrical systemsBuilding structural elements and roofingBasic HVAC componentsWater heatersFire protectionThis engineering-based cost segregation study included the following methodology:Physical Inspection through a site visitDocumentation review including architectural plans, accounting records and construction documentsA cost analysis which utilizes engineering principles in order to allocate costs to their applicable asset classificationsCalculation of the depreciation schedule using MACRSAs a reminder, bonus depreciation started to phase out in 2023.

I agree with screening the Sec 8 applicant the same as all applicants for good housing history. 

Zillow has a rental application.

If you present the listing well, put it on multiple platforms and are asking a reasonable rent you will get plenty of interest and applications quickly. 

Makes sense, but still frustrating.How should I handle the move-out part and make my application strong enough to convince the lender?

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).
