We did Airbnb. 95% booked year round but low rates at $50-65 per room per night which was the gong rate in our neighborhood so with paying for cleaning and supplies we didn’t make much at all our first year.

I’ve already met that requirement at this point if I include my 6 hour round trip driving to the property from my primary residence every week. 

I would want a park that would be mostly full year round... but those probably aren't for sale too often.2- Accuracy of the financials. 

Myrtle Beach, Charleston, Wilmington, OBX...If you are looking into flips or brrrrs I'd suggest outskirts of Charlotte and Round Rock, SC (about 30 min from CLT). 

The year round demand with two peaks (ski season and lake / beach season) combined with a lower regulation threat make them pretty good places to own an STR.

I do 12-month leases all year round and it actually produces more income.

For instance, the Poconos have remained a popular option because of its year-round tourism draw, with skiing and lodging in the winter, hiking in the fall, and camping around lakes in the summer.As others have said, going into markets with one draw is risky.

Fannie Mae's guidelines verbatim are as follows:Must be occupied by the borrower for some portion of the yearMust be suitable for year round occupancyBorrower must have exclusive control over the propertyMust not be rental property or a timeshare arrangement (this has the following disclaimer in the guidelines:  If the lender identifies rental income from the property, the loan is eligible for delivery as a second home as long as the income is not used for qualifying purposes, and all other requirements for second homes are met (including the occupancy requirement above).Cannot be subject to any agreements that give a management firm control over the OCCUPANCY of the propertyThis means that as long as you intend to occupy the property some portion of the year, you could absolutely rent it while you are not using it. 

Their coaching is not cheap, but I think the thing that separates them from the one-time seminar gurus is that they offer a series of classes designed to deepen their student's knowledge so that they end up with a well-rounded education, versus what you can get (and retain) out of a single 3-day fact-filled seminar.

Frankly, if I can find good ones then anyone can.Our place is a long way from town and finding someone to drive 2 hours round trip ain't easy.
