if i take the profit from a sale and use it as part of a purchase of another property do i still have to pay taxes at that time

generally, yes, unless you do a 1031.

and remember, cash received is not necessarily the same as profit.

thanks for the 411 i guess thats why i have an ccountant i just needed to hear it from somone else

There is also an exception for your primary residence if you meet certain requirements.
