But now you own a property that has 20k in deferred maintenance; so you only cheated yourself.

In order to defer all tax you must purchase at least as much as you sell and you must use all of the cash in the purchases. 

But the fee was deferred until the project sold.

Capital gains to be deferred: 200k - 50k - 10k - 100k = 40k. 

That’s not nearly enough time to get them cash flowing or even all the deferred maintenance you know it has !

The remainder of the gain you will defer by doing a 1031 exchange to purchase new investment property. 

Connect with a good wholesaler who knows and understands your numbers.Just keep in mind the other potential variables ( slow/no appreciation, deferred maintenance, high crime, etc)

Last March I purchased 2 triplexes for a great price.I know there was deferred maintenance, roof, gutters, paint, and some cement and landscape issues..But the deal was too good to pass up.

So you'll be living in a house partially paid for by the deferred taxes (thank you silent partner Uncle Sam).2.

If not, you may be looking at a deferred maintenance situation, which means you'll need to bump up those CapEx/Repairs budgets to something like 8-10%.
