Hmmmm....mcmortgages? LOL
A few thoughts on these homes (And I know exactly the ones you're speaking of. Many are built to bare-bones specs, and shoddy workmanship.....people BUY NOW & figure they'll "upgrade" later. I can't tell you how many mcmansion families I know that are STILL planning to "finish that basement O. day"!
First of all, I wonder how they make the payments. And IF they make the payments AND manage to "live" a real life. I have never been nor will I ever be "house poor". Where's the fun in that? If I can't afford a comfortable life in which I can do things, go places, take a vacation a few times per year...something's "wrong".
Secondly, what a bank tells you that you can 'afford" per month and what you really CAN afford are often worlds apart. There's a HUGE gap. And yes--there are people out there who are foolish enough to listen to a mortgage guy. If I had listened to the bank 20 years ago when I (single woman) bought my first home, my diet would have consisted of mainly Alpo. I mortgaged HALF of what they approved me for and even so--many months things were VERY tight! 25% of your NET income is a reasonable amount to put aside for a mortgage. No more!
Thirdly, there are, apparently, people out there that "see" others and envy what they do not have. Logic goes out the window. They "gotta" have it....NOW. No O. will admit it, but it's often a case of "keeping up with the Jonses" clearly. In our area, you can get a basic home for 100K up to 350K. Different areas have different median prices for homes. Could I 'afford' the mortgage on a 350K house? Probably...with some lifestyle changes. But I'd rather keep my middle of the road paid off house rather than be a slave to the bank and a hamster on an exercise wheel.
Fourth, there are a lot of misconceptions out there. People say they're Ok with the payment b/c we get to deduct "all this interest" every year & it's better to never pay off your home. Ummmm.....OK. They can keep thinking that because they are making the banks very rich and themselves very poor.
ETA* I almost forgot my largest point! If I could afford a 500K house, I certainly wouldn't want to live in a subdivision with hundreds of other houses all around me! How do these people find their way home? Land, people! Land! LOL
