Typically it's meaningless until it goes hard and percentages of pp have definitely dropped over the years. 

Your definition is correct for "legal non-conforming".The "legal" part of "non-conforming" is dropped when it doesn't apply so most commonly people call these units "non-conforming", "finished", "in-law suite/unit", or "bonus unit".Non-conforming: Any property that doesn't meet current zoning requirements.Legal non-conforming: A non-conforming property that was lawfully established under previous zoning regulations and is allowed to continue its use.Based on his posts @Mario Morales is referring to a non-conforming unit.

I wait well over a month before I hear any responses and then every single time they ask me to drop the rent.

My biggest hesitations with keeping this property is the rental market is pretty saturated and I’ve heard of some investors having to significantly drop their rent or have prolonged vacancies.

If you have a sample deck or know where I can find some great examples, please share them here or drop me a message.

My real question is about managment because the reality is Im looking for a property on the cheaper end that i can drop 15000 into and have some cash flow and have managed 

Oh and we had to drop our initial price of $2,650 for mid-term rental to $2,250.The reason for the drop.

Not sure if this is the case in your market but once we get into the fall time frame in my market the demand drops off significantly.

You as the buyer also have rights under fair lending and you should never be forced to use a builders lender. 90% of the time lenders drop the ball and end up not being able to close on time or their overlays cost the buyer the deal and in some cases earnest money.I would walk away from a deal that forces you to put $50K in earnest and use some generic lender who may not even be able to close the deal.
