HELP!! Thinking about seller financing home that has been a rental the last 5 years?

[Paul Scammacca]

Considering seller financing on rental the last 5 years ( we paid it off). For the tax folks................what taxes will I be responsible for the following year? If I plus 100k on the sale is it all captial gains at once like a traditional sale even though I wont collect the funds at once? New to me might not make sense to do it, thoughts???  Thanks guys...........................P.
