If you can see yourself living in this house for the rest of your life, and if the mortgage payments are similar to rent, and if you are close to work (no major commute), then this is a no-brainer.
Seriously, this is coming from me — the female version of scaredycat (I worry about everything and tend to be exceedingly conservative about finances/life, too, and this can be a huge handicap in some instances).
Make sure your wife is happy about it (are you happy, Mrs. Scaredycat, and will you love your husband and NEVER hold it against him if you guys buy this house?). If she says “yes,” then go for it, and don’t look back.
Don’t forget to invite us all over for the housewarming party. 😉
Looking forward to all the pics of your happy chickens and persimmon trees.
