I've been researching the topic for awhile trying to understand the economics of the business and where the "value" can best be unlocked, but it always seems that all the articles I find are a lot of talk with very little substance.

You either fix the problem or you're back to square 1 and there is no harm to you or the business

@Wayne Brooks Guess that makes sense, but no harm in trying.

For example, a horse or a llama may be rejected from a small studio apartment.Second – if the building has 4 units or less and the landlord lives in one of the buildings.Third – it is a single-family house that was rented without a realtor and the owner owns less than 3 single family homes.Fourth – if the animal in the unit brings an undue financial hardship to the landlord.Fifth – if the animal causes damages or harm to others in the building.See if your lease has a move-in clause.

Plus they will argue that it appraised, so no harm to you.The decision you have to make is if the property is worth the same value given the smaller square feet.

Is there anything in it that could harm me?

Reason being the State's don't want agents using their superior knowledge of the market to harm citizen sellers who theoretically have a much weaker understanding as to the true value of their properties.

If not lead safe, then mitigate.Liability insurance would never cover  “a municipality passing new laws...”Liability insurance might cover against harm you caused by unknowingly having an unsafe condition... but might reject the claim if it is deemed that you should have known.

I am saying that "Good intentions" often end up harming the borrower that is already in a stressed emotional and financial situation and someone without the appropriate licensure and experience could cause more harm than benefit.
