And, I will profit less at the sale of this property because I will have not paid down the principal.

As you pay off your loan balance principal, that loan number of 120K becomes smaller, leading to more equity.

Once closed, quit-claim deed the property to your LLC, provided that you are the sole principal of the LLC (about $150ish fee depending on the state) It would be worthwhile to call your bank and see if this can be done.That way, you have your 30/30 mortgage, added protection, and building equity, credibility, and most importantly -- cash flow.

They currently pay $850 month and pay their own utilities After Principal interest taxes and Ins I figure about $250-$300 month in extra income.

@Aniello Belfiore I usually pay around 10-15% of total project costs...or $160/hr for a principal...$120/hr for a non-principal...seems to be pretty consistent across most A/E firms.What type of project is it? 

Plus the cash flow improves (not just the interest but principal payment also).

On the payment - this really depends on if your HELOC is interest only or principal + interest, payments would range from $300-$500... just google HELOC payment calculator and I'm sure there's one out there.

After setting aside 50% for costs, then you pay the mortgage (principal and interest).

-take your cash flow (Net after expenses and mtg payment)-Add your principal payments back in you made on your loan, as Principal payments are not deductible-subtract your depreciation, about 3% of purchase price (actually, building value only/27.5 years)= Taxable IncomeThis, of course is just relating to the specific property and doesn’t consider any expenses you may have trying to find properties, education, etc.
