Some of the information is populated automatically and some is done manually. I definetly would contact my Real Estate agent
Possibly it could be a great thing to do depnding upon the value of the home and interest rates
I don't know that I would be worried but I definetly would be meeting with my Realtor to go over the marketing and price positioning. There are three things that sell a home #1 location #2 condition #3 price. You can't change your location and if the condition is good then the only thing you need to look at repositioning the price.
It would depend on the market in that particular development. You also need to verify that the condo association allows you to rent it out that condo development
A new home owner does not need a large down payment to purchase a home. The least amount of down payment with a FHA loan is 3.5 %. Veteran and USDA loan require 0 down.
The best way to make sure you don't over pay for a home is by using a Real Estate professional that will provide the data of current sales in the area of the home you are buying.
