I think they are doing this so they are not in lease violation by having another adult staying there.

Require a driver's license from an adult.

It's not a passive job (regardless of what the IRS says).Everyone honestly should be running and creating their own calculators - why people invest tens/hundreds of thousands of dollars and then rely on someone elses (or better yet - pay for someone elses) calculator blows my mind. these are simple calculations for 90% of landlords.

Those folks simply can't be relied upon to relay inquiries, showing requests, etc or to put your best foot forward.  

It's really only relied upon in new construction and even then I would place more value on a discounted cash flow with assumptions for time to stabilize to market occupancy.

So with retail sales ( unlike if your building something were your relying on rent) we did just fine market absorbed it..

@Don Konipol we solved it by learning from the Intentional Living Community (the OG's of independent adults living together). 

My thoughts are if looking to rent on a bedroom basis, it is most likely going to be to single adults, whom I would like opt to live as close to downtown St.

I think we are at the point, where labor costs are actually going down as most of the labor relies on big national builder's for their work, and with home sales slowing down, we are seeing labor rates competing for work, which is driving down the costs.

Don't rely on a single tenant verification service.
