I get a kitchen from IKEA, it takes 1 week for them to send me the parts they didn't have in the store.

Is there an online interface for tenants/owners?

Search for this publication online to find a discussion of the calculation of the number of loans a borrower has.B2-2-03: Multiple Financed Properties for the Same Borrower (10/31/2017)

Going to Rockwell Institute for Real Estate (Washington state - online).

Online averages about 20 to 30%.

My tenants utilize an online payment app (Roof), I run credit and background checks online (SmartMove) and keep all of my records in a folder on Google Drive.

If truly all it needs is a new roof to be complete and ready to sell then a few ideas off the top of my head could be:1)  Borrow the money from friends or family to replace the roof2)  Put the cost of the roof on a no/low interest credit card and pay it off as soon as the house sells3)  Go through a home improvement store (like Home Depot) that offers financing for larger projects like roof replacement4)  Don't replace the roof and just lower your sales price or offer the buyers a credit to fix it themselves after closing

Will you provide a porta potty, or not (think trips back and forth to the nearest convenience store or gas station, or worst-case, they use a corner in the backyard, which leaves the wrong impression on your neighbors)? 

There's a lot of Class A apartments coming online so 'affordable' rentals have lots of applicants.  

A walk away from many gas stations, grocery stores, 1 mile away from the hospital and walking distance from schools.
