Cash flow is important, but not the only factor (ie cheap homes are not for everyone). 

I'm aware of the several factors that make an application more likely to be approved by A/B lenders. 

If you can't verify someone's identity, credit worthiness, or other risk factors, then that's a legitimate reason to deny their application.2.

Rely on the data as a tool for “no.”I am developing a data-driven analysis to weight as many factors when reviewing a deal as possible, measuring everything from demographics and area vacancy to parking and signage.

(and your question should be premised with some size factor like between 1200-1500SF). 

I would be more likely to factor the utilities right into the rent and keep their rent a flat monthly amount.

Problem is the equipment wears down over the years and starts looking old and the owners do not allocate for the cool factor reimaging and putting new equipment in to boost sales up. 

most lenders  will  utilize the  schd E rental income average  method  for  including rental  income for  qualifying ...if the  proeprty is  recenlty  purchase the  vacancy factor  approach is used 

It will be a factor if other aspects are not adhered to but if it is the only one not very likely.

So if you find one whose willing to operate in truth, honesty and integrity then they will not have a problem with the following (13) Rules of Engagement I have created when dealing with PMLs.1-I require that we transact all business using a local Title Company of my choosing, using their resources (i.e. title search etc), their loan servicing capabilities and an attorney of my choosing to draw up contracts.
