Every time the owner of an investment property interacts with their tenants, they are setting precedents. If one accepts partial payments or late fees, they is essentially waiving they’re rights to be paid the rent on time and in full. Furthermore, if it comes to pass that the owner has to take the tenant to court for not paying rent, any such acts of kindness on the owner’s part will work against him in court. It’s a sad state of business, but a true one.
That why if you own investment properties Minnesota - I recommend that you operate via the letter of the law. You don’t have to accept partial payments or waive late fees, for one thing. Late fees and the right of eviction, are the investor’s only leverage. If you give those up, you won’t have a leg to stand on. It’s best to follow these guidelines - just to be safe.
