Insurance ($97/mo) + Mortgage ($3,400/mo) + Property taxes ($444/mo) + trash, water ($100/mo) = $4k/mo. My mortgage is new and is only paying down principle ~$120/mo. This means I pay about $900/mo for my room, except I have had an average of $1k/mo in home repairs since I bought the house.
The real value I am capturing is my personal housing _might_ be cheaper than if I rented myself.
I am sure in 10 years, I will be in a good spot, but not today.
