You'll need to find the right lender that can accept revenue projections for short-term or midterm rentals.

And it directly translates too revenue. 

This immediately struck me as odd as I wasn't aware of any form of compensation to the PM for any maintenance related activities, just 8% of gross rent and 1-month of rent to lease the property, per our contract.Naturally I wanted to understand the nature of this arrangement, specifically how much mark-up is being charged, so I referenced a specific sewer repair bill from 2015 that was $2,600 and asked him if he could provide the vendor invoice so I could understand how much the vendor charged and how much revenue the PM recognized.  

We do offer bank statement HELOCs for business owners who don't show income on paper but can show revenue coming in(bank statements), doesn't sound like that applies here.Freddie Mac allows for assets to be counted as income, 70% of total divided by 240.

Bottom line STR restrictions are just going to get tougher over the years so one needs to choose very carefully up front and also if your buying based on cash flow I would think you need to make sure your OK at long term market rent and base your buy on that.. if you get STR added revenue thats a Bonus.. there are areas of the country were STR will probably never get attacked like we are seeing in many markets.

It means you could deduct 100% of the cost against this years revenue.  

It's ability to produce revenue is a direct result of how one utilizes that asset.

if you are able to, would go the whole house rental. it would likely lead to more revenue as most guests would prefer privacy the entire stay. 

You need to examine the state in question's revenue code.These are all good questions for discussion with your tax advisor.

Ideally you can find a multi unit (2-4) to increase revenue.
