I just checked all my properties against the latest FEMA flood maps here:https://msc.fema.gov/portalNow sometimes your county may also have a layer of this in their GIS system.In any case I noticed three of my properties seem to lay inside ZONE X (which is lower risk) then previously ZONED AE.Down here insurance is expensive, we got liability, windstorm and flood and just flood on one subject property is $1500-$2500.I am guessing I can't just call up my insurance agent and say check out this web site...so I need to obtain an updated elevation certificate just from the map being rezoned by FEMA.For ZONE X I actually am not required to carry Flood but I guess I still will just for the peace of mind especially if the new rate is lowered.Anyone else been through this, would appreciate if you know of a way to get a formal rezone for a specific address that you can use for insurance instead of another elevation certificate which requires a new survey I believe.

LOL, Jay might refer you to himself...No HML has unlimited funds, they can't borrow fed funds, so if they can obtain the business goal of some out landish rate, why would they use their "limited inventory" of money at a lower rate? 

It was my understanding (which is limited mind you) that I would need an authorization to release information form from the buyer so that I could obtain a reinstatement quote/letter.

How do I politely obtain this information from the current tenant, and is there any specific documents (or proof) that I should request?

For example, the buyer must obtain financing for the property while the seller must ensure through a notary that the property is free and clear of all legal encumbrances so that it can be conveyed to the buyer at the time of closing.

“Landlords of rent stabilized units who try to use a temporary lapse in the rent stabilization laws to break existing leases, to raise rents improperly, to intimidate tenants, or to coerce tenants into leaving their homes, will be subject to the full force of law for any such action,” Cuomo wrote in a letter to be sent Sunday to landlords.The letter, obtained by the Daily News, states that despite any temporary lapses, the new rent laws once approved will be retroactive to June 15 — so “your legal obligations under existing leases and under the passage of the new rent stabilization program will not expire on that day.”De Blasio says if rent-regulated apartments law expires it would be 'end to New York City as we have known it'The governor directed landlords to continue to follow the current law until a new law is enacted and any changes are fully understood.

I would imagine if you do not immediately qualify to file claim for a lien then you would have to sue on the contract and obtain a money judgment which you can then use to collect.  

As I was thinking about what exactly my goals were and how to obtain my thoughts went to becoming a certified appraiser.

When obtaining a loan, the bank will want an LLC or individual on the note, so may be difficult. 

Assuming you do get the hang of how to obtain all the needed figures.
