You do not solve money problems with more money as that is not the issue. The issue is that you are spending more than you make and that is putting you into debt. In order to gain a hold of your financial situation, you MUST change your spending habits and make some sacrifices.
Quite honestly, most rental units are as high or higher than the cost of your monthly mortgage. I have a four bedroom, 2 bath house, 1800sf. My mortgage was under $1,000.00, including taxes and insurance. Houses like mine are rented for over $2K in my area. So, based on that, it makes sense to own a home.
A real estate commission is going to eat up much the equity you have in your house. And, that is even IF you can sell it for $30K more than you paid for it.
Let's say you sell the house and pay off your debt, or what I believe will be just part of your debt, not all of it. Then you rent a place that cost more than your mortgage and still have the debt to pay on top of that. How do you think you will ever get ahead and save another 20% for a down payment? Remember, the down payment you made on your house is part of the current equity because the rest was borrowed. So, in essence, you are giving away your equity to debt and will not have it handy when you go to buy another house.
I say stay where you are. Rent will be higher than your mortgage, so if you could afford a higher rent, you can afford to pay off your debt with that money. Right? Also, real estate is taking an upturn in value, so by the time you are ready to buy again, you will be paying more.
Stay where you are, tighten the purse strings and pay off your debt. Then, take out a home equity loan in the future to increase the size of your house or move at that time.
When I divorced, my finances dropped dramatically. But, I kept the house and paid for it on a very tight budget. I managed to tighten the purse strings and went on a total spending freeze for two years while being a single mother raising two teenagers. I opted to keep the house in lieu of child support or alimony, so I had zero financial support from anyone. I went to running my household on $150K per year to just under $22K a year and I DID IT. That was 15 years ago. Now I own my home outright. So can you.
