Normally if there is not a specific address they are not really for sale and may never be for sale.
I have provided you a link to active properties for sale in Irving below.
If there are any you would like to see inside, just let me know.
Are you presently working with a Realtor?
Have you spoken with a Lender to determine what you might want to spend and to get an approval letter?
What is the approximate time you would wish to move?
I'll be glad to help in any way I can. Thanks.
