Or find a local design firm that has done cabins where they can show you proven rent results from cabins they've designed and have them charge you by the hour. 

If i do long term rentals i could only charge 1,600-1,800 a month in rental income.

Spoke to a HVAC contractor saying about 7k for HVAC work and 1K for electrician work total 8k but overall may improve tenant experience and maintenance charges to me but bit more price to put upfront

I would do this every 12-15 months if my spouse wasn’t totally opposed to moving frequently.

Prior to me putting 50% of the unit into a special needs trust for him I charged him rent.

Then he charges me his bank's $13 fee, so a total of $63.     

Lightning Docs, which we use, charges $500 per set and I believe Doss charges $400 but we haven’t used those. 

Here are some thoughts I had.Potential Backlash - I agree with @Erik Estrada that charging fees might draw criticism from some community corners. 

Also, they charge a 10% markup fee on repairs.
