We have just been through what you describe. We were (are) moving out of a "hot" market and there were many things I wanted to do to the house to ensure top dollar and a quick sale. My husband on the other hand didn't feel we needed to put any money into the house; he felt like people would want the opportunity to make changes to their liking. We agreed to meet with a realtor to get their opinion. Our realtor ended up saying the market was hot enough that we didn't need to make any changes. Sure enough we listed it and received multiple offers on the same day, within one week of listing, at full price and we don't even have to make any repairs. So glad now we didn't spend the money to make updates/repairs in advance. Also, our house was appropriately priced...not too low, not too high.
With regard to moving truck costs, 15K seems way too high. We are using UHaul and including an auto-transporter for a car and the total cost will be $2,400 + fuel costs for a 2,000 mile move.
You can do this without spending a ton of money and bank some of that 15K in the process.
