I bought my house in 2011 because it was a smoking deal. 5 years ago, I built a 24x45 garage. I have just under 2 acres and may buy another 1.5 acres next to mine. However, I'm in a position similar to yours where I not only need more garage, I need more house. I also want 20+ acres.
My plan is to finish fixing up the house and, as much as I hate to, live with my current situation for the next 3-5yrs. At that time, I'll be able to sell (at a serious profit) and hopefully interest rates will be a little more normal and I can find the property I want.
Buying the land beside me will add to my resale value and make it stand out over area comps. Finishing my remodel will bring the house to a little more modern look and add convenience, while addressing some issues that existed when I bought it. Outside of that, I don't intend to sink any more money into this property because it still won't meet my needs and I won't see a return on the investment.
I say all of that to basically say: you need to evaluate your specific needs, wants, and future plans. Be 100% honest with yourself. Don't throw money at something that won't benefit you in the long run or just to "almost" fill a need/desire. In the end, you'll be down whatever money you threw at it and still not have exactly what you wanted.
What is normal?
