Mom:
Upgrades ARE considered when appraising a home. MOST DEFINITELY. As are ANY upgrades you do in your home.
Since you are moving back to Texas - i would suggest that you get a home inspection done PRIOR to your appraisal. This way - you will know what you HAVE to fix in order to get it sold and sold fast instead of lingering on the market.
The lifespan of things are considered:
* roof (usually 15 - 20 years)
* garage door (20+ years)
* A/C and heating unit - 10 to 15 years
* windows (10+ years)
* Appliances that are conveying (washer/dryer, refrigerator, dishwasher, oven, etc.)
If these things were just recently replaced - it will add value to your home. If they are nearing the end of their lifespan - it will detract and deter potential buyers as to the amount of money they'll have to sink into it.
Other things that are considered are comparables (Comps for short). How many houses similar to yours are on the market. What they sold for.
Ask yourself this question - would YOU want to buy your home knowing that it had pool issues? defective sprinklers? plumbing issues? If the answer is NO. Then they need to be fixed or you need to lower your expectations on selling price and figure that into the cost of selling. Also keep in mind that some items MUST be fixed in order for financing to go through. So get the home inspection done.
Things that are NOT considered in an appraisal - if your home is dirty. You don't need to "clean it up" for the appraiser - however if the carpeting is coming up and the hardwood floors are badly scuffed...or the linoleum is missing some chunks...yeah...THOSE will be considered.
GOOD LUCK!!!
