So the more 1031 gains you have in the property the smaller portion of the property (proportionally) you will be able to accelerate with teh cost seg. 

As it is attracting a lot of Flippers in Detroit at the moment.Areas between 7 and 8 Mile in the NW are just accelerating and the Banks have started to Lend in Detroit.Which is Great news.So house prices are moving steadily up, Flips are in the 70s and 80s price ranges, ARV of 120-130 after 10-15K work.And seems like you are ready to swing - so good luck.

Finally, while my rental properties are allowing me freedom and growing itself, my regular job will provide acceleration of my personal debt reduction.

If you have a max price higher than your initial offer, an acceleration clause can help. 

Last night we were talking about strategies to pay off mortgages in accelerated ways.

Forgot to mention that lenders like to accelerate the mortgage pay down with short term remaining on the lease.

We did a couple of Cost Segs and accelerated that depreciation.Depreciation is one of my favorite words!

The beauty is that you can accelerate the payoff for the property you just finished or you can use it as your own bank.

Can a mortgage company call your note due/ accelerate it if you sell a primary residence within a year of buying it?

I would take into consideration the interest rate on the debt versus the return I anticipate on a new property and also whether the new property's cash flow will help accelerate debt pay down.
