I found a few sample operating agreements that will work with minor modifications, and my lender seems to be OK with that. 

Let me share a real-life example that could provide some insight.A recent client of ours had one of his ten properties, which we manage, become vacant, necessitating a $30k capital expenditure (cap ex).

Are there any modifications to the written lease?

Modification and damages is one of the top items we discuss at the move in briefing.

Another option is to use hard money loans for additional acquisitions, but that seems like a high cost way of doing things, and would certainly necessitate being very ready with a lender for blanket loans.I've got really good deal flow...for the first time! 

As the previous response mentioned you may need some serious modifications to get one installed but you may not. 

This is why we like to focus on double net deals in markets where DG has shown a commitment to the market via lease modification agreements.I’d put the remaining equity into a DST if you go the triple net route.

The condition is such that it does not necessitate the need for occupants to have to stay elsewhere.

Smaller lenders who are less sophisticated believe any transfer of a due on sale clause is an issue and that has necessitated additional discussion, but I am as certain as any lawyer can be about my work product and its effects over the years.I have also prepared resources that are on the web including webinars where I walk through the structure in detail with graphics.

In this case these homeowners have an HISTORIC track record of NOT paying their mortgage time and time again over the years to where the lender who is foreclosing had to already not ONCE but TWICE due loan Modifications for them and also set aside substantial funds from past arrearages they COULD NOT pay by taking back a Subordinate 2nd lien as on their residence property ...Not someone I would want to advance more funds to UNLESS - I am able to GET TITLE
