this topic is ironic. i am/was in your shoes, sort of.
i wanted a shop. i have a little more stashed away than you do. could i keep on saving for the shop and do it cash? sure. do i want to do that? no. i also dont want to wait until im 50 to enjoy a large garage. i am 32. i do have a family. i bought this house a year ago. 1 yrs later i pulled out some equity the house, the house appraised for over 30k more than what i paid and i when i bought i put 20% down so i am sitting on over 65k in equity on the house. i was very fortunate to buy this house. i pulled a 2nd mortgage on the house. im not ashamed to say it. alot of people on here think if you borrow for a shop you should be castrated. to those people, i will say mind your business. they dont help you make your money, only you can decide how you want to spend it. i was able to borrow money for the shop at the tune of 225$ a month for 15yrs. (even if i went the whole 15yr, the total price of the loan divided by sq/ft is still cheaper than what some people pay in diffrent parts of the country) i dont plan to go the full term. less than 5 yrs is the plan. why spend your money and deplete your savings when you can borrow and keep your safety net., at the price of whatever interest rate you get. i would not get a personal loan, those rates are probably 10% if u can even get a personal loan these days. i will have my mortgage and my shop for under 800 a month. and worse case, have it paid off before im 46. (worst case) the money just hit my savings acct today, and the ground breaking on the shop starts monday.
in the bigger picture, before we moved here, i was living in a smaller house, for more money, and i had to pay for a 10x20 storage unit (125/month). i will have the shop for basically 100 more a month than i was paying in RENT , a little over a year ago.
i say go for it, enjoy life while you can. dont wait until you are in your 50s. good luck.
