Your equity is the bank account used to pay fees and costs to sell. As a percentage of your sale price the fee looks relatively small. The sales price is not where your expenses are paid from. That’s just a number used to calculate certain fees. The only real number is your GROSS EQUITY.
If your only fee was commission and the commission paid to a broker is 6.0% as Zillow suggests, and your Gross Equity is $150,000, your 6% is a nearly triple 16.0%. Here’s the thing, the commission is only one of the fees, expenses, and costs. The greatest threat to you equity is errors made in representation, flaws made in contracts, deficiencies in negotiations.
Instead of focusing on the asking price, or the sales price, keep your eye on your equity. Guard it. Make everyone who wants it earn it, like you did.
