The buyer of a property, or an option to buy the property, may have an insurable interest in the property.The key thing to look for is the date of loss. 

I wasn't involved in this but just kept up to date as to what was going on.

If there are a lot of people in the apartment, all the time, perhaps you could park nearby and take pictures of them and note the times and dates.

I have lived in it since that date.

PM me and we'll work out a date.

I don't know what is required in terms of a rental and what (if any) date there is to grandfather what I mentioned in.

You can find that a seller is moving out of town and arriving at a new place in say 45 days, offer to match the closing date or a few free days as a hold over moving out.If they are going to rent, and you have another place cut a deal in the offer if they would be interested, the listing agent should know what the plans are.Find any problem the seller may have and solve the problem is the easiest way to put it.Work with the listing agent, if properties are moving at 20% above the asking price, make your offer in line with the market to begin with, really want it with your emotional side, heck, it's only money!

Of course you may need to change distance and may need to go back further, but tried to get the closest date and distance.

I tend to not mess with things unless they are really dated and ugly.

I recently found out that in MD, I have to provide 30 days' notice to my tenant even if the lease has a definite expiration date, no renewal clauses.
