I doubt any wholesaler is making $100k per year.Lets make sure the math is right first.

Oh and BTW- I realize my parents had outgoing expenses over the 35 yrs of owning the condo (though no roof or exterior work came out of their pockets)- but I really did do out the math recently and it was around a conservative $275k profit plus appreciation.

Another issue, someone mentioned notes were sliced and diced, yes in the secondary, but so are portfolioed loans when they have large balances.

Above all else DO YOUR MATH!!!

Of course, there could be an error in your math.

Secondary problem is they stop reporting issues like drips and suddenly $20 jobs become $1,000 jobs.

Also, it seems unlikely that they're doing 30-year fixed as a 4.80% portfolio loan (i.e. keeping it on their books), seems more likely to be a secondary market loan.

If that's confusing, do the math in the other direction.

Here is an example pulled from another math site://QuoteFor example, suppose you have an investment which earns 10% the first year, 50% the second year, and 30% the third year.

On the one hand, there's plenty of math to go around... on the other hand, there's plenty of abstract meta to engage even the most mathematically-challenged amongst us.
