I didn't say you should...or have insulted you in any manner for what you choose to do or whether you make a profit or not, etc. This is just two different sides of the subject we are discussing. Or...I thought it was.
There is, but you seem to be ignoring the other side of the argument and only focusing on yours.
My side is this: most of us landlords don't make much money on rental income. Much of what you pay is what you would otherwise pay if you owned a house: taxes, insurance, utilities, repairs, updates, mortgage.........
In some cases (like mine) when I had to take a loan out for major repairs, those loans have to be repaid.
This year I was lucky, I actually made a little profit. My tax preparer has a lot of landlords, and she told me I was the only one last year that showed a profit. All her other landlord clients were in the red as they are most every other year.
Big companies probably make out, but rental property is just part of their portfolio. They are very diverse in their investments. When one investment isn't working out, then they dump that investment and put their money elsewhere.
So if the government made regulation that stopped their profit, they would be selling out probably to somebody that would charge even more for rent.
