The fee to submit an application is $600.00.

You may want to look at small independent stores.

I inherited a partnership in a 22 unit commercial building with 8 restaurants, a grocery store, a couple of personal care services, and various other businesses.

Have a way to double checking their information they give you on the application.  

But I need a portal where I can do the following -Customize the tenant application  ( Cozy does not  allow me to customize)- Have tenant Upload Pay stubs, DL, etc. 

Buy some 5 gallon buckets with lids.Buy the following and store in buckets or 2 liter bottles.50 lb bag chickpea or garbanzo beans     50 black beans. 50 pinto beans.       50 rice50 Idaho potato50 red potato50 onions50 carrotsBulk pasta, or make it yourself(cheaper but a lot of work).Meat:Large spiral cut ham 20 lbPork tenderloin- 20 lb cut into boneless pork chops.Cheapest roast 20 lb.

But make sure to check out the BP book store here also.

Without the tenant explicitly stating (preferably in writing) you can trash whatever is left, you likely have a requirement to store items left behind. 

This criteria happens to pretty much exclude all S8 applicants. 

Manage their properties Provide welcome gifts/ goodie bags for their guests before check in Hauling extra supplies/ misc items to return to stores or other properties--Any other ideas that I can pitch to make myself more marketable?
