Yea every extra dollar you put into your loan is best spent! None of this "pay your house off in 30years" stuff, pay it off as quick as possible, then enjoy the benefits.
We got our house paid off in 5 years, I am not a high wage earner either, still built a few toys along the way, gotta put the effort in tho but that does not mean having a life. Basically planning is key ad sticking to it, we didn't waste cash on trivial things either.
Paid off 2nd property by 37 and bought a cruiser, only now are we considering a camper trailer, been camping in a $150 tent with 2 kids so far......
Some pain now will pay off later on
