I bought my house last year, I was 22. Let me tell you right now, ditch the truck. I had to pay credit cards down to get my DTI under control. And my car payment was and still is $173/mo. Having lower monthly obligations allowed me to save a decent down payment quicker & helped my DTI ratio. Sure, I didn't always have clothes as nice as my friends, i definitely didn't have the coolest car, but Im the only person my age that owns a house in my peer group i associate with. I already have $8000 in equity in my home. I was approved for $157,000. My next step will be to purchase an investment property using a HELOC/401k.
You're in a good spot having just that 1 monthly obligation, so imagine this. You drop the car payment, get something cheaper, save $18000 in 9-10 months and you have your 20% on the conventional loan of $90,000. Now you're not paying Mortgage insurance either using FHA if you were to occupy one side. I dont know, i'd kill to have an opportunity like that. Dont blow it.
