Our lender said the appraisal would include a request for the appraiser to do a Fair Market Rent (FMR) analysis of the property and we would be allowed to use 75% of the income as you mentioned above.The lender also mentioned the possibilities with a conventional loan (which of course would require more down) but we are being told that they will let you do the same thing as it relates to the rent on the duplex/triplex with the 75%, BUT they would also allow us to use a signed lease (plus proof of 1st month’s rent collected) to offset the payment on their current home that they will eventually be vacating. 

On an average month I will spend thousands of dollars in supplies so If I can pay for vacation without paying count me in.

Maybe golf vacation getaways? 

I just got back from a weeks vacation there .Its a small city .  

If they're not staying, they have 30 days after X to vacate.

You give them 30 day notice with a clear expectation that they vacate no later than 11:59PM on [DATE].

That meant working LONG days; six days a week; hardly a day off; no vacations, and a lot of sacrifice.

I'm thinking that I should charge 150% of the monthly rate that an annual lease would be - this would still be less than half the price of an extended stay hotel , and do it as a vacation rental, with the entire rental period paid up front. 

I always send our 30-Day Notice To Vacate by certified mail with return receipt.

SO currently me and my father have been looking at putting our cash together and purchase a log cabin in Gatlinburg for a vacation rental.
