Not until you educate yourself on the market and the correct way to value a property.You would probably be best using sales comps and/or GRM's.

Subtracting the $4k in closing for the first purchase, the $2k in closing for the sell a year from now, and the $8.4k in selling fees from a conservative sale value of $140k leaves you with $125,600 minus your purchase price of $118k and you pocket about $8k.
