I guess different strokes for different folks.. but the mortgage on my house (a really nice house) is less than a 1 bedroom apartment in most cities.. then again im an on-grid city-lover so obviously different than most here..
I dont look at my mortgage as anything more than glorified rent... its really what it is.. im not sure I could live on my own plot of land in a bus with things like internet, clean water, septic or sewer, electricity (outskirts electric rates are often much higher than in town).. and the like for what I pay at the house... going off-grid mitigates some of those costs.. and lowering quality of life also mitigates costs as well.. (sweaters instead of heat.. sweating instead of A/C)..
anyway the biggest thing if you go to buy land is what they will and wont allow on it.. ie if you are going to rough-it for life without utilities.. or if you buy land close enough to a town or township to have electricity.. what kind of water table is there? is a water well feasible? or is it arsenic-water or too deep to drill, are you allowed to put a bus on it? we have heard of certain places that say "sorry no mobile homes".. or RVs as permanent residences.. if you plan to also build a tiny home and then have your bus as a travel vehicle, than the last point is likely mitigated.. but if the plan is to have the bus as your home and park it there X number of months per year, check the legalities..
technically it should be YOUR land. but even land you bought for cash seemingly outside of city limits doesnt seem to really be your land... grrr..
