Pan Ra - great question. Roxie has a good answer but I see a few things differently.
That area pretty much developed 20 years ago, so if you like the schools, lifestyle and amenities, and see great value in eastern Alpharetta, that's great - just deal with the drawbacks of the quality lapse in building materials and in some cases construction and in some cases, neighborhood development that occurred during that era.
Once you settle on a choice, hire a great inspector and test, inspect and survey the entire property.
1. On a typical house up that way - budget $1500-2500 per year, or more if the landscape and grounds are high level - I bought a 1991 built Pulte home at Riverbrook in Duluth back in 1994, so that's about what I spent 4 years in a row until I got outta town and moved to L5P.
2. contrary to Roxie, I think that many owners sign maintenance agreements - termite service, landcape, and heating and cooling service contracts are all quite common and I recommend them if there is not a tremendous desire for hands on, owner level maintenance - these are also a good check off at resale
3. depending on the newness of the water heating, HVAC and appliances, and things like bath fixtures, and the siding, roof, garage door, etc. - you or may not want a home warranty - call up the service providers and get them to piutch you - if you don't like the math, then don't buy a warranty - try to get a seller to buy one of these for you, regardless
4. never buy a house in a hole - those have a time limit...everything else , just about, could conceivably live forever with today's array of plastics, coatings, and other nifty household gadgetry that make a a house in a great neighborhood something that should be there in the 22d century.
Will that Pulte home I bought in 1991 in Duluth still be there in 2112? I'll give it a maybe. I don't know Riverbooke nowadays, but it's a swim/tennis 'hood and folks pretty much like that...so, yes, maybe.
Will the 2 story house on a basement, the 1907 Victorian with asbestos siding, the one that has not been painted in nearly 30 years but still looks stellar, the house in Inman Park, will that house that I bought after I left Duluth in 1998 still be there in 2112?
Yeah, it's in a great neighborhood. - Yesterday at 4:14am
