Your gain will be your purchase price plus improvements plus costs of buying and selling (see the settlement statements subtracted from the sales price.
So, 250K - 35K -65K - costs of selling and buying = less than 150K gain
Long term capital gains are taxed at 15% so the tax on 150K = $ 22,500 regardless of your tax bracket.
If this was a primary residence that you own and occupy for two years you could exclude the gain and not pay federal tax.
Mississippi levies no capital gains tax on in-state investments
I hope this helps for estimating your tax on the capital gain.
