Great web site Larry gave, but they don't work in Orlando, which is where Jo Ann wants to be.
Antonio asked some great questions. YOU have to know what you want before someone can help you.
I have a few more questions you should ponder to make the right choice for you, but first - I'm a little confused as your profile says you are a home buyer in PA... is that one of the area's you are also considering moving to?
Are you SURE you'll be an empty nester in 2 years?
( I've run across a lot of parents who thought the same, and it didn't happen. . . or it happened, but they came back )
If you will be retired, have you figured out the most comfortable payment for you, bearing in mind that the cost of everything will always go up. When helping Seniors and first time buyers, I always advise caution in this area.
Do you have to sell a house first to move? If so, do you know what your net proceeds will be, and
how much of that you want to use to buy another place and how much to keep back for a nest egg?
Have you talked to a mtg lender to get approved? Orlando is a HUGE place, and depending on what you feel comfortable spending, you can narrow down a bazillion communities to choose from to a mere million ;-)
Did you know that unless you move to a rural area, that you will also have HOA or Condo fees in addition to your mtg payment?
I'm a real estate consultant, and would be happy to run you through some thought provoking idea's to help you out if you'd like. FL is a BIG place, and depending on what you like to do, Golf, Swim, fish, etc, you have to think of re-sale as well (in case you move to a place you decide you don't like).
Let me know if you'd like some help sorting through this, and I'll be happy to sort you through it just like I've done since 1979 for many others. I was born here, there isn't a lot I don't know about where you should move, but YOU need to know the answers to the above to get the right fit.
What do you want to do when you retire?
When do you want to move?
You say you are 'thinking' of Orlando... what other area's are you considering, and why? Weather? Prices?
