Are they moving to a completely new area / state?
I can give you a few pointers in the house hunt..Even though we did this many years ago.
Look at many homes in your general area you want to target. I think we looked in a general area of 4-5 cities. I remember one split level that after about 20 homes we viewed that kind of hit us both....But something just wasn't right...the realtor happened to say something about there was water damage where the whole bottom level was re-done...Upon more digging I found out that the whole street of homes have flooded many times over the years....That kind of explained why it was a little under the going price for its size....There was no way I would take a chance like that.
After maybe 10 more homes viewed I happened to see in the local paper a "for sale by owner" ad for a very well kept home
....Having viewed many homes in that city over a 6 month period, I knew the price ranges....In the end we offered full asking price because I believed the owner under priced the home, but he also knew he had a home that had a lot of street appeal and he would be saving the commission fees. That evening we were signing papers....That was back in 91'.
I wasn't really thinking about staying in this home more than 10 years. I though we would be moving up to new home. But I can say this house is just right...It's only 4 miles from work, 2-3 blocks from shopping, 1-2 miles from both North & south freeway....At the time we were only tent campers. 80% of the homes in our city you would not be able to park a RV on. Thank God we have some space to get our 25' tt up the drive and park it in front of the garage....
In closing, I can just say you are going to have to take your time in searching for that home that works for you...Especially if you are new to that area. We lived about 2 miles away and I had grown up in the next town...So I kind of knew the area.
