As a contractor, i do a lot of remodeling, and am remodeling an old rental now. The customer wants to do the same as you.
My 2 cents:
revinyl kitchen- Yes, buyers hate bad floor coverings.
new carpet throughout- see above
interior paint: definitely. Paint is one of the cheapest ways to make a house look good. Use a good stain blocking primer, especially if smokers lived there.
vinyl siding replacing aluminum- No, with a caveat. unless the siding is badly decayed all over, just replace damaged pieces. However, look at soffit, facia, etc (outside trim) and repair/replace as necessary. You want to fix things that will draw the eye of the prospective buyer.
new kitchen counters- no, unless they are in very bad shape.
new kitchen cabinets-no, but you might consider repainting/staining. Also you want the doors and drawers to have no problems opening/closing, etc
new dishwasher- no
replacement windows-no but consider new weatherstripping on all doors and windows
replace front and rear porch- This can be iffy. You damn sure don’t want anyone falling through a rotting porch. You might need to replace some flooring, depending on condition, and also make damn sure the railings are stout. And make sure the steps are sound!
replace rundown privacy fence (or just remove) w/o seeing the property, I can’t offer an opinion.
You didn’t mention one of the main things, the roof. Leaks kill drywall. I have seen whole ceilings just fall down because of a few months of drips. I LOVE those jobs!
Also, if the house is very old, electrical/plumbing/HVAC needs to be checked out.
Other buyer peeves are such like doors that bind, squeeky floors, dribbly shower heads and so on, basically stuff that irritates people.
My point is, you want to get max bucks for the house for the least amount on repairs without doing halfass work.
I don’t know if you plan on doing this work yourself or contract it out. If you contract it, some advice:
MAKE SURE THE CONTRACTOR IS LICENSED, BONDED AND INSURED! I can’t emphasize this enough.
This protects you both. If you get burned, you have legal recourse same with the contractor.
Get at least 3 bids and compare.
Demand references. Most reputable contractors will happily give you refs, and quite a few even have a “portfolio” of pictures documenting previous jobs. We are quite proud of our work!
Read the bids thoroughly.
Pardon the long post…I am sure I missed/screwed up some stuff, having had a few brews, but I hope this helps
