I have an offer out on one in Crowfield Plantation and I'm hoping to secure it.

You pay PMI, they have the security of a property with 25%+ equity.I realize you'll have closing cost, but a small price to get out from under the PMI (and screw it to your current lender). 

So I'd need a secure 6 port router at least.This is self interest also, it costs $70 for just broadband from Comcast or Verizon here.

Trust that RECFs are here to say and are going to Rock the Real Estate, Lending, and Security Institutions to their core.  

Although nothing is ever guaranteed in real estate, the money I pour into this property seems very secured.

Going forward, in case something happens to me (death) what is the best way to secure here money?  

I thought when they signed the lease, they need to give me a security deposit.

I am trying to get creative with a recent off market deal that was sent my way and was wondering how I might secure my financial interest in a property which I would like the owner to carry the note until time of sale.

Is there a security deposit that you will collect from them?

We always install security doors with alarm systems on our homes.
