I would dump the house like a hot potato and use the cash after you sell it for a guaranteed goldmine investment that will give you tons of instant cashflow and make you rich.
You can take the cash you have and earn a guaranteed significant amount of more profit only if you decide to use a business model that you adhere to. If you don't have a business model then you will not achieve what a good business model can reap for you.
The purpose and goal for a good business model is; look for investments where you can double your investment capital every 1 to 2 years. That means, if you have $150k equity in that house then you want to earn $75,000 to $150,000 every year with that cash. If you don't have that business model then you will not seek out that type of profits.
While it may sound difficult to earn a 50% to 100% profit on your investment capital every year, it is quite easy and takes only a few minutes of your time every day. I can write an entire book on this subject, but this is the short version. Suppose, you have $50,000 to invest. Then, to earn 50% to 100% on your money in one year you only need to find a property that is either priced $50,000 under market value and/or you need to find a property where it is both a little priced under market value and where you can do some minor cosmetic work, increase the rents and increase the value of the property by rehabbing and increasing the rents. So, if you purchase a property worth $350k for $325,000 and increase the value of the property by doing a little cosmetic work and increased the rents you will earn the $50,000 you put down on the property in less than 1 to 2 years.
It is virtually impossible to increase the value of single-family homes by increasing the rents and even when you rehab a single-family home and make it the most-beautiful home in the neighborhood it is still difficult to sell the house for more than the comps in the neighborhood. That is where multi-family homes are the most-profitable investments you can make because when you increase the rents for multi-unit properties you automatically increase the value of the property based on the rule-of-thumb Gross Multiplier. The best part of multi-unit properties is you can often purchase 4-plexes for the same price as a single-family home and when you increase the rents you are increasing 4 rents every year at the same time vs. increasing only 1 rent.
As stated in a few recent posts, if you want to go to my profile, I just purchased a 6-unit property in the most expensive city in the country for $975k. I am paying cash for the property and will earn, but the chart I posted indicated that if you put $250,000 down on this very expensive 6-unit property you will earn $155,000 per year and that comes out to a profit of $1,555,000 in 10 years after all expenses, more or less.
The annual cashflow on the top of chart is the cashflow at the time of purchase, only, and does not include rent increases at the time of purchase nor annual rent increases. The annual totals include the cashflow with rent increases.
