The best advice I can give you (if I may..) is to absolutely, under no circumstances settle for something, just so that it is done. I don't care what the realtors say, if they keep pushing you, find new realtors! They are there to help you. Just keep looking, I had a friend who looked for a year-- alot of times he would go to open houses without his realtor. Interest rates shouldn't go up too much, since most banks were anticipating the rate hike for some time, and you can usually pay a point or so for lower rates (good if you plan on staying for a long time)
2 Years ago we decided that instead of buying a vacation prop (in celebration!) we would sell our condo and buy a single family. We started looking and probably looked from about May till July/August. We found 2 houses we loved and missed out on both. After that, our realtor started pushing us VERY hard to find a place, it was unbelievable. In the end we settled on a house, that was better than most we had seen, but not what we really wanted. I spent most of the first day crying- it was left in terrible shape. There is alot of work to be done, and it is farther from work then we realized. (It is across town from where we used to live, but there is no direct route to the highway to get to work) We have a bathroom we don't even go into because it is in such bad shape. I get overwhelmed when I think about all the work that needs to be done. A few months ago the realtor called to see how we were doing, she casually mentioned that it had been a very bad time for them, they were really crunched for money and really needed the commission. She apologized for pushing us so hard.
Best of luck to you- the right house will come along!
