Congrats on deciding to buy a home of your own!!! You have already being paying a mortgage, by renting from your landlord and providing them the funds to pay their mortgage, now you will be paying your own!!!!
Now, SF homes do not have to be FHA approved. You just have to find a seller wiling to work with a FHA buyer, which most are.
Condos/ Townhome developments are a different story, they do have to be FHA approved.
Go to HUD.GOV from their website you can search for developmenst that are FHA approved. You will need to know the name of the development.
Please note sometimes they will say approvaed but may be expired. If they are expired the HOA has not provided the documents to FHA to renew. In some cases your lender can do this for you if they have a FHA Condo department.
As a first time buyer I would suggest you try SF home first, and avoid the additional HOA fees, which in some developments can be over $300 per month. If you must go condo/towne home I would urge you to choose a PUD townehome. In a PUD towne home you own some of the land your unit is on and will have no one living on top of you or below you:)
Best of Luck to You.
