Ask them to please be more mindful and if it happens again, add it to their ledger per their lease.

I have an 8-5 that brings in just under 100k and I work as a part time realtor(sold 3 houses last year and had a rental deal too) and I bartend most Sat nights(300 a night, working 4-11)If I sell the 2 family, after 15% cap gains and 2% to the buyer agent and lawyer fee and pay off all our debt(wife and myself, not mortgages) We would have about 150k left over.If I sell the cabin, after agent fees and cap gains we’ll probably walk with 60k.Would keep pushing forward?

Market rate is $190k per unit.I'm really excited about the potential of this investment, but I want to ensure that I'm making sound financial decisions.

Ask for a breakdown of fees and an explanation why the interest rate increased.

To do anything like a refi you would pay all of their fees again and start a new loan at 15% - 20%. 

You'll have to eat the fees or sell the home. 

That kind of analysis just look at prices without taking into account the buying power of the local buyers, which makes it completely flawed.Short-term rentals haven't been banned per se.

I hate to continue to pile on the fees for credit checks to do them on four sets of parents after charging the tenants for this. 

If it's taking longer than that, consider whether your price is too high or your marketing needs improvement.Take 10-20 minutes every day to study the market on Zillow, Zumper, Apartments.com, REALTOR.com, etc.

Good luck and enjoy  making money on 2 properties that go up in value  80,000 - 125,000 per year.
