If the SPD is not available, the plan administrator or human resources department should be contacted for a copy of the most updated version.

If you want to acquire the property associated with the certificate there will likely be administrative costs associated with the tax deed application and in at least one state with which I am familiar (Florida) it is possible that significant other costs could be incurred but that process is only important if you elect to invest there.Another pitfall in tax lien investing is that in most, if not all states the certificate expires after a specified duration.

It made my life really painful for a while. 

It made money during rental but was a pain in the *** due to turnover.

The lender sometimes requires an administrator to take payment from the corporate tenant and then distribute any leftover proceeds to the investor who owns the property.The corporation also sometimes makes payments directly to lender on a loan you would be assuming for structure so that the tenant protects their credit rating and borrowing power.A NN lease is where usually there is some expense to be born by the landlord either the roof, structure, parking lot, maintaining utilities for access and repairs, etc.The caps tend to be higher but you have costs as a landlord.GSA leases (government sponsored agencies) typically are not pure NNN but have a NN component.

First, they were a pain to deal with and refused to set an appointment for me and refused to even talk to me about the foundation.

All of the pain is incredibly loose on all walls and most of it came up no problem.

It is a bit of a pain, but for FHA and VA there is no way around this requirement.

Eager to find a solution to which this was no problem, the city administrators saw fit to pass an ordinance requiring apartments to have a minimum square footage of 400, so that landlords would not be able to "take advantage" of tenants.
