Understanding this background on the situation... does anyone have previous experience with single income households where the "bread winner" goes on maternity leave and then has issues paying the rent.

Mortgages are the largest debt line-item for households.

Your post comes off as someone who made a very unsophisticated deal to try to make a tiny spread and wound up incurring costs and liabilities they didn't anticipate.

I have seen a couple of new-build STRs that need refinancing, and they were hard to finance due to their being tiny homes, cabins, rural multifamily (with no comps), etc. 

This increased the required household income to purchase the median-priced home by $6,400, to $119,700, after also accounting for the cost of tax and insurance.

These are tiny municipalities.

The tenant is a survivor of family violence.This ground is allowed to be raised when one member of the household commits physical harm or reasonably places another in fear of imminent physical harm.

But here's the kicker: the median household income in 2021 was only $56,746, and most households below that are renters.In the article local agents in the multifamily sector talk about why landlords are hiking rents.

I chalked it up that he was going through some personal stuff but would not be renewing his lease, his lease ends on the last day of July.Well, a month went by and then I got to wake up to another large unhinged text of him accusing of another tenant of mine of a disgusting and sexual act in the bathroom openly in the household's group chat.

I am a builder and I have some land and want to build a tiny home park.
