When the business takes off, then move to your dream mansion.Now, some businesses, dependent on a retail location, when you rent, runs the risk of the owner selling the building or not renewing the lease so you can lose everything.

Let the house run down and you will likely lose your parents earlier due to falls, etc as well as any inheritance of value.

It may cause problems because you'd deliberately be losing money and could run into problems with the tax man.

So right off the bat I will be losing 16 cents on the dollar when I bring the money south of the boarder.

The last one was a man in his 80s that was starting to lose his mind.

If your home has appreciated in value you can sell it and not have to pay income tax on the profits, BUT only if you lived in it 2 of the previous 5 years:https://www.irs.gov/taxtopics/...So, if you rent it out for a few years you will lose this opportunity to avoid paying the tax man.If you decide to rent it, be sure you want to do it for a long time and be sure you want to be a landlord in general because otherwise you may regret giving up that opportunity to avoid paying income tax on the sale.

Expect investment loans harder to come by, and the credit score and LTVs more strict.Jeff Lazerson of the Orange County Register made some interesting points about this announcement worth nothing:Lenders may lose their appetites to make these loans because of a worry Fannie and Freddie will say no due to their new rental and second home loan allowances.Many lenders “have already increased second-home financing by an average of 1.45 points.

Make sure you are all clear on expectations, decisions, and what happens if the project loses money.For this deal specifically, if it's just a one off with this family member, it might be cleaner to let them keep their $10K and just throw them a finders fee.

If I were to get sued in my current situation - I believe the case would have to be above $1.3M before I would have to personally pay out / potentially lose my properties (or other assets).  

@Monica SethNo, for a couple of reasons....1) moving back in for 6 months Still won’t get you to the 2 (24 mo.s) years of the last 5 years (60 mo.s)..you still have that 3 years 4 months (40 mo.) gap in there.Every month going forward, you lose one month that you lived there before you rented it, as you look back 60 months from your  Sale date....so you can’t meet the rule unless you move back in for 2 years.2) If you moved back in for 2 whole years, to meet to 2 out of 5 rule, you still won’t get the full exclusion because you met the 2 out of 5 rule After it was a rental.
