The average duration of a mortgage is 7 years. You'll appreciate at 5% per year on average and pay around 30k in maintenance expenses during that time frame. You will also pay 5% of the house during the sale for selling and general expenses, so for each 200k you will pay 10k.
So on a 200k home, it will be worth 268k at the end of 7 years. Your mortgage will be 170k. After commission, you'll be 254k, then backout upkeep which will be 224k.
After 7 years you made 54k. Wowzers. If I rent, I can move whenever to better areas for better jobs. That's the play in your 20's. Make that 185k boys.
