We are a family of 4, with my MIL coming as well. An apartment isn’t an option.

New home is intended to be for the next 17 years, though relocation for work is always a possibility. That relocation would entail additional financial flexibility due to a promotion or leaving a job for higher pay, so not really a concern.

We could pay both mortgages in a pinch, and could always sell down the road if the financial benefits of renting were no longer there.
