I can see both sides on keeping and ditching. The problem I would have is ditching my home, if I could afford it.
I suppose if you live in a dump and you could easily afford a much nicer house that could eat at you.
I guess I’m a sucker with morals, and would probably keep the place, I’m a first time home buyer though, so that easily affects my decision I guess.
Are you happy in your house? If all the other houses were expensive and you had your house would that change your decision? Would you be happy then?
If you are happy in your house, stay, the grass is always greener. You ditch the house, end up renting, getting a bad landlord.. maybe end up in a house that gets foreclosed, then you have to move again, etc.
Your only headache right now is that your house price is declining. Go outside, sip a cold one, and enjoy life. You have a house you can afford, your family fits fine in it, and just enjoy life for once. Stop looking at real estate blogs and sites, it doesn’t benefit you, are you looking for a house?
You took yourself out of the game, you have a house now, enjoy it. That is why you bought it right?
