We have a mortgage on our current home with about $100,000 in equity.

I talked to my mortgage broker and he says I may be able to use the building's equity (he estimated $70K in equity, that the building should be worth $120K based on the monthly gross income). 

There is a lot to consider and my basic math on the income/expenses seems to show that I wont have an income from the property and all of my gain will be in equity.

At this point of the cycle I'm not aggressively acquiring properties esp with my own cash, I'd much rather use the appreciation in equity. 

I got a really low price, fixed it up, and gained over $100,000 in equity.

The house is under priced and I feel with 10-15k I can gain 60-70k in equity in a few months of work.  

And I can't think of any other businesses where an owner would voluntarily pay a vendor in equity or create an equity partnership with a vendor.This is just not smart business practice, for many reasons.This isn't the biggest risk in my experience, but here's one example of what can go wrong when someone has a fiduciary responsibility to two parties in a contractual relationship:https://www.biggerpockets.com/forums/67/topics/641355-flipping-partnership-going-to-court-on-debate-of-renovation-costs

Income tax withheld by an employer from an employee's wages or salary is treated as paid in equal amounts on each of the four installments. 

The 7-unit I bought as a value-add property and added about $100k in equity over the last year, so I'm not opposed to doing similar projects in the future if profitable.I know how to analyze a deal and calculate NOI when scouting properties (though admittedly these properties were acquired many years ago, before I knew much about RE investing).  

Hi,I've got around $1.5 million in equity in a few properties around Denver, Colorado.
