Some have more than $1 million in equity while others have less.4.

The initial numbers I have ran, assuming he will accept an offer to buy it for 130-135K, that would give me a decent amount of un-captured equity on the back end, and with rents for what would be improved to be around $1400 and assuming 4.75% (1% above current market) My cash ROI is 28%, cash flows $150-170 a month with estimated expenses( I want positive cash flow, but interested in equity capture so am acceptable with anything +$100)  and Cash Flow / Mortgage is 124% with my doing my own property management. 

I have 250k in equity.

If your primary residence does indeed exceed 20% in equity you can then request them to drop the PMI from your payments.The best way to get the formal appraisal might be to call your lender and ask them what they will accept as an official appraisal and then work with them to get that scheduled.

If we sell our primary residence, we will have $100K in equity.

I have about $100k in equity and $100k savings I’m looking to put down on my next investment.

I owe about $260K. 6 years from now I believe it will grow really well in equity becuase I am inside the city of Houston, which continues to boom.

I am sitting on approximately $40k in equity I would like to tap into at closing.

Some have more than $1 million in equity while others have less.4.

I would suggest these action steps to get a more clear idea of a path to take.FInd out how much your primary home has in equity(for heloc), how much it can rent for, and look for duplex/triplexes you could live in one of the units and rent the others.
