For instance; if the home was sold for $450,000 and they owed $400,000 with $30,000 in closing costs, then they would take home $20,000 in equity/profit. 

We’ve got about $175k in equity due to the large down payment needed to assume the mortgage. 

We bought at the peak of the market in 22, and can’t stomach the loss in equity + paying an agent to sell.

This way you have an instant increase in equity.  

Meaning if I’ve gained say $50k in equity (just and example), and I put it on the MLS, and the end buyer purchases it, how does that look at closing? 

My first property not only brought in equity with minimal rehab but also had a tenant paying rent from day one, unlocking 25k in equity. 

It's harder to find really good deals with built-in equity on the MLS, but it's also much easier to avoid making mistakes and buying turds and money pits. 

First, I have about 250k in equity from my primary residence.

The 4 financed properties are worth - $606,040 - a $50,040 gain.During that time, your tenants paid down your mortgage with each of their rent payments as well, so you have an increase in equity on the financed properties as well.Then there are the tax write-offs.  

@Frank ChinBased on the opportunity value of cash your equity, if your mortgage free, is most likely creating negative cash flow from your investment property.With the opportunity value of cash at a minimum of 10% for every 100K in equity you must deduct $833/month from your rental income to insure a accurate accounting of your TRUE income.Investors must keep in mind every property has two separate income generating streams.
