IN about 2 years or so I will be doing a Bill Gully and retiring from BP..

My husband used retirement funds.

Maybe that is one of your interview questions.If you are very top producer there can be some advantages, like employing your kids, SEPs or retirement plans and maybe if you have a big team some shield of liability if you set it up right and practice what your attorney teaches you to do to keep everything separate.

I am looking to buy long-term rental properties as a source of income from now through retirement that will leave a legacy for my two daughters.

I put 25% down, and at that time we were thinking to keep this as a vacation home where we plan to retire eventually.

If you were to spend the next 10 years of your life sacrificing lots in order to gain knowledge of particular industry (Industrial or Multifamily) which would you rather know when all is said and done and you were to try and retire with this knowledge. 

My name is Robert Hubbard, and I'M 3 YEARS AWAY FROM RETIREMENT of 20 YEARS ACTIVE DUTY!!!!

The problem with that is two-fold: first there are likely existing assets that are not replaced that qualify for shorter asset lives so you're leaving money on the table, and second you have no cost basis for the removed assets replaced in the remodel as they're intertwined with the initial building cost basis so you'd technically still be depreciating retired assets which is tax fraud. 

Reason for the LLC is I have 180k of equity in this home, additional 150k in retirement savings and another 60-80k in cash in my bank account and I want to make sure im protected if I rent it out and the renters sue me (im told that is a thing) - the nw home would become my new homestead2) Put a heloc on the home (im told I should be able to get about 100k on top of about 60-80k cash I have), keep it as my primary and use the money as a downpayment for flips and either payoff upon completion or put a tenant in and refinance out3) Refinance out 90-100k from my current home, mortgage payment would go up $300 per month ($3600 a year) and just use that money for flips/buy and holds or even just stick in the S&P at an average of 7-8% return so I am making 3-4% more on my money then it being in the houseI am super new to all of this, have been saving my pennies up for awhile and need to get going. 

I have long term goals of cash flowing for retirement.
