If you haven't already done so, you may want to engage a realtor to help you find properties that ARE offered for sale. Oftentimes, when people search on line, they find properties like the one you saw :that are not for sale....yet.
On Listing Book, we realtors can set it up so that you are automatically notified every time a property meeting your criteria becomes available. And you can change the criteria anytime.
Let one of us help you.
By the way, if you haven't talked with a lender yet to be prequalified/preapproved for a loan (in case you're not paying cash), you may want to do that first to find out:
how much you can afford
what kind of loan you can get and at what interest rate
how much of a downpayment you need
and what your comfort level is (are you comfortable with having half of your take home pay go towards mortgage payment? If not...what is the maximum you're willing to pay?)
A lender can help you with these questions. And if you don't have one, a realtor can give recommend more some whom you can talk with.
