If you're moving out of the area, then it's pretty obvious you'll need to sell your single-family home. There are other signs you need to sell your single-family house as well, but you might not notice them immediately.
If you want to talk to your real estate agent about putting your home on the market, it's better to do that sooner than later. Here are some signs you might want to sell your single-family home besides moving out of the area.
The market is in a seller's favor
Sometimes money can be a great motivator to sell your single-family home, particularly if you have a lot of equity in your home and the market is in a seller's favor. Just make sure that you have another home to move into that won't take most of your profits in selling your current home or that your home has gained so much equity you can still come out ahead if you buy another home in the same market.
You don't want to rent
You can always move out of your home and rent it out to someone else, but it might not be in your best interest to do so. If you want to move but cannot afford two mortgages, then renting your home might be your only option outside of selling your home. Speak to your real estate agent about ways you can sell your single-family home and how you can rent the property out so you make the best decision in the end for your needs.
You want a different school district
If you want to go to a school district that you desire, you might have to sell your single-family home in order to make this happen. Look at several single-family homes for sale in the school district you really want so you can decide for yourself if it's best to sell your single-family house and look for one in a better area for your needs or if you should stay put. Your real estate agent can give you information about how much your home is currently worth on the market and can help you both sell your home and buy another one.
Your home is an investment and you can sell this investment at any time you see fit, so make sure you check periodically on your life situation to see if you should sell your single-family home or just stay put for a while. Your real estate agent can be helpful in helping you make the best decision for your needs.
