Loan interest payments are absolutely not something that should be converted by rent - you just take someones labour to pay for something in order for you to eventually own it.
Same with taxes - both on rent profit and real estate itself.
Maintenance, insurance, electricity, water, etc tenants cover, bcs that is the thing they are using & costing landlords. And those things are absolutely not 6%~12% (as average re yield) of the real estate price. Its just profit from labor transferred to non-productive factors.
