I’ll definitely take that into consideration moving forward.

If you are buying the property from the owner, an IRS lien can be removed if you can establish that the owner received no consideration in the sale.   

SmartKey locks are easy but they cost considerately more.

Other considerations.  

The seller told me they may even be willing to forego the first 6 months lease fee in leiu of using that money to finance the repairs.There are a lot of other considerations, such as the option after 5 years and of course the ARV, but I'm only really interested in the cash flow for now to build my own portfolio, and not the option or the potential from ARV.This is not a solicitation, but I would love advice on whether it remotely looks worth doing and if so, how can I sell it to someone when I find someone to ask for 500k collateral and a partnership?

This in itself could be a very important consideration for an investor.Character : There have been many business owners or real estate operators over the years with experience who have gone belly up or been involved in illegal activities even.

Will take this into consideration. 

I live on Long Island in NY and am hoping to build up a portfolio of long-term single and multi-family rental properties in the coastal Maine - New Hampshire region, where I spend a considerable amount of time and am hoping to make my retirement destination.  

I have found good deals and have been able to get the owner seller to hold considerable seller financing.

You might consider reaching out to them and seeing what membership could offer you which I believe would be considerable.
