In the side I house hacked I updated the bathroom, I installed turf in the back yard, added a large shed, and furnished the Unit.

A full back office. 3 workbooks to use in the 40 hour class. 

Im not expert but Ive took out a heloc and dragged on going on my advise and it suckedHi @Mario Morales, There are 2 things I would pay attention to in the scenario you describe. (1) Most cash out loans are limited to 75% -80% LTV meaning you wouldn't be able to get all of your cash back out. (2) The interest rates I see in the market are closer than what you've listed.

Also, having a rehab budget already laid out with explanations on how you got the numbers would help and is definitely a plus when I look at deals even though I typically wont use their numbers it at least shows a little more effort. 

Did you know before it happened, that new regulations were coming regarding condominiums that now makes a large number of people both regret buying and now not being able to afford the  payments on the "great deal" they bought a while back?

@Paul Cijunelis  thank you for this response Paul, well I firstly got interested in CRE when one of my high school teachers told me about how he does it and that kind of started my interest, I really love CRE because I've noticed it's a very lucrative and risky business like high risk high reward, but not just that I really love seeing a bunch of properties being brought back to life with renovations.

But, if I would have done a cost seg back in 2015, 2016 - I could have bought a bunch of properties with the tax savings.

The benefit is it is revolving so you can take it out and pay it back multiple times.

But you have closing costs for Refi, and sale, but in sale you get all your equity back out. 

Then once you spend the money for that.. then the contractor will simply file a UNJUST Enrichment claim so your back to square one..
