Is my goal doable?

Could be, it depends on your bills, spending habits, and how much your wanting to spend on a house. If your disciplined there's no reason you shouldn't be able to hit your goal.

 

Why do you not currently have your CDL?

Edit: nevermind, just saw why. Always read the entire post before replying eh?

 

Should be doable
Depending on your existing bills and your level of commitment

i got an intestinal infection a couple of years ago and the treatment was a week in the hospital, lots of antibiotics and no food for three weeks

I lost 30 pounds in those three weeks .

when I first started driving I was dead broke and highly motivated to make some money
I worked the first 100 days without a day off , and I moved into the truck to save the $165 a month I was spending living in a trailer park . Uh, I mean a mobile home community .
I was able to save a lot of what I earned .

 

Do you really think you can save several hundred thousand dollars in 5-7 years to buy a house outright?

Rose colored glasses would not do it, much less the dark ones you are wearing.

 

If you can bank $500/week you'll be at $25k per year x 7 years is $175k. I'm not sure what will be available in 7 years for $175k.

 

Are you in Tacoma? My daughter and her family bought in Renton last year: Nice home but nothing over the top. $500k.
