Cost segregation utilizes the MACRS approach.

Here's a detailed guide on how to screen applicants: Application Screening Guide 

The behavior is a bit off, but not surprising for a mom & pop landlord.We tell our residents exactly what we need from them for the application. 

Why pay rent when your landlord gives you free housing, free maintenance team, free mortgage, free electricity, free water, free trash?

The first mistake is the property is free and clear.  

& how you become financially free is by letting whoever your renting to (I'm guessing that was a step also?)

If he won't let you call HR, then deny his application and move on.

I guess it triggers the "sunken cost fallacy" part of their brain.

@Jorge Vazquez we stopped doing signs over 10 years ago.We had a separate phone number on our signs, so were able to track traffic & applications from them.We were getting more & BETTER leads from our online ads then the signs - so an easy choice to stop using them (also time & money savings).

This includes preparing the property for renters, pricing it right, marketing, application screening, collecting rent, dealing with unpaid rent and other lease violations, security deposit disposition, inspections, and so much more.
