I don’t know the details of her situation, but it’s something like in a market that averages over $1000 for housing, she rents out at below $1000. I mean to say for her properties she could choose to rent at the market rate but this would mean the people who wants to rent to, people who aren’t able to afford >$1000 for housing, would you know… be unable to afford it.

As for barely making a cut for themselves, I’ve only known a few landlords but none who owned the house and title (without a loan with the bank). the landlords I do know, herself included most likely got 30 year fixed mortages on their properties, meaning their interest rate stays the same for 30 years.

Each month those landlords need to pay the mortage and will need to pay for repairs or repair the properties themselves. Say the mortage, due to the landlord’s credit rating is pretty good, and comes in around $800 a month. Say that on average the landlord has to pay $50 a month on maintenance. The landlord needs to charge $850 to make no money, to afford no food for themselves, or otherwise “break even”. What I’m saying here is that in this market, a property just like hers (x beds, y baths) rents out for $1200 a month. I’m saying that she’s more likely to rent her property out at $900 or $850. Although when people fall on tough times, she’ll also just waive the rent or work with them with what they can pay.

Meaning if they just sold the place to the people renting it out would be even more affordable?

Probably not. You’re assuming that the renters have good enough credit to get a loan from the bank at the same interest rate that the landlord can, that the renters can afford a down payment (sometimes that’s $10k+ right there). Keep in mind these are the renters that could not afford a $1200 a month place themselves. You’re assuming that the bank would give them the loan in the first place. You’re assuming that the current interest rates are reasonable (at time of writing, in the US, they are not - the difference between a 3% and 6% interest over 30 years is enormous and would make their rent far greater than $1200 a month).

You’re right that there are some renters who can afford to buy her properties if she put them on the market. Those renters hypthetically live in the property next to hers with x beds and y baths and they’re looking for a place to live. She could sell the property to them, but she’d then need to evict her current tenants, and since there’s a lack of landlords like her, they will probably need to move to another town or be homeless.

There’s not a clear right or wrong answer here.
