I see we have New Hampshire and Massachusetts here, and now Maine. I guess nobody is buying houses in New England.
We had to be on the other side of the country by the end of August last year, so we put our house (southern Maine) up for sale last spring, in the hopes that it would sell before we left in August. Didn't happen. It sat on the market for one year, May '08-May'09. We didn't even get one offer, even after lowering the price. The house is very nice and was priced lower than the appraisal.
We did not want to continue paying for two houses, so we decided to take it off the market and rent it out. It was a tough decision to make because of all the rental horror stories we've heard. My husband and I also decided not to go with a property management company, so we've done everything ourselves. We listed the house on Craigslist and by the end of the day, we had the house rented.
We had people from all across the country replying to our ad. We were actually shocked at how many people are looking to rent a house. The funny thing is that the first person that called and came out to see the house was someone that lives in the next town over from us, and turns out that my husband knows him through his computer business.
We looked at rental agreements and rental contracts online, and drew up one that fits our needs and requirements. We spent June and most of July in Maine, and on August 1st, the tenants moved into our house. We had already emptied most of our stuff out of our house, but still had to rent a small U-Haul trailer to transport stuff back here (Arizona), furniture and things that we had left behind to use whenever we were in Maine.
We had two yard sales, gave away lots and lots of stuff to friends and family members, threw away tons of junk, and put more than one pile of stuff next to a "Free" sign by the end of our driveway. Incredible all the stuff one accumulates over the years!

Then we had all the empty and half-empty cans of paint and other such stuff sitting in the shed and basement that had to be disposed of in a proper manner. I also repainted several rooms in more neutral colors and gave the house one last good cleaning.
So far, so good. Of course, it's only been a month.

In our lease agreement, our tenant pays the rent and all utilities. We will provide and pay for snow plowing and, if necessary, snow removal. We also take care of landscaping, mowing, tree work, etc. We have a lawncare guy that comes on a weekly basis (less when the weather cools down) and he is quite the character. He told us that he'll keep an eye on things and that he "has our back".

We also have a friend across the street that we know will alert us if she sees anything alarming going on, and we have relatives in the area that would help us out if we need them for anything.
Our tenants signed a one year lease, so at the end of it, we'll have to decide what we're going to do- keep renting the house or put it on the market again.
Good luck to everyone renting. I hope this thread continues to survive. It would be interesting to see how the rental process works out for everyone!
