Houses get old, houses go into maintenance and they depreciate in value over the time. I am pretty sure this is not the case as mentioned in the OP.
They are only valued if they are some sort of big houses like mansions with its own property (land/garden/ponds/golf ground) I hope you have imagined already what kind of property I am talking about here.
Those are the properties which gets highly paid over the time. However, most of them get valued based on the real estate land and its location.
But usually that isnt the bucket for everyone out here. So look for the properties right, not every of them would appreciate in value all the time.
Dude my house was 142k in 1992
it is now 660k in 2022
I put 100k into it.
I also lived in it for over 30 years.
Rent would be 12 x 30 = 360 months and at least 1500 a month or 540k and no value for that spent.
Of course home prices vary.
I am sure if your house is Keiv it's price dropped like a mofo from dec 2021 to dec 2022.
