They will think you are running a tenant screening/tenant application fee collection scam. 

My systems are ok, rather I have to give credit to the individuals I work with as well as proper tenant screening.

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

The quality of work on prefab is not great, but easily sufficient for rentals.  

There's plenty of quality inventory under 400k in that market. 

They will be able to give you price point, occupancy potential and overall quality of the locations and what its drive is.  

Winning with cash really depends on the quality of the property and the timeline of the seller.

I am not sure about what you are reflecting in the cleaning number but for me 1) it is shocking what cleaners charge but it is not where you want to try to save money for quality 2) it is a pass through, the guest pays it. $250 per turn would be for larger unit and very good job.  

Pre-screening: On 3 different occasions the potential applicant is asked if he/she meets or surpasses our minimum screening criteria. 3.

For the most part I've always done the leg work on screens possible tenant.
