However, due to my ignorance, I am now finding out that the realtor I am working with is also representing the seller as a dual agent.Is this a common practice in REI to have dual agents in pocket listings? 

Now, you'd be working direct, which opens you up to some risk because you'd be working with the listing agent, or possibly in a dual-agency situation.

We just moved from FL to NV in a dual motor 3 and had no issues with Supercharging, but that 373-mile S would be nice.

Dual Agency? 

Low voltage lines can lay on the ground, but high voltage lines need to be in conduit and depending on location, may also need to be buried. 

I like the dual-method you proposed of setting aside some money at the get-co and then a certain amount every month.

Since you don't want the seller to see what the TRUE buyer is paying, title has to do some kinda BS with dual escrows.So you're going to need to have someone help you with that subterfuge.

If you don't plan on upgrading the panel and re-running the wire, you will have to use a modified kitchenette set up with low voltage cooktops and apartment fridges. 

Depending on local law and the office policy of that Agent, they may be able to act in the capacity of a Dual Agent; or allow you to be "unrepresented"; or treat you as a "customer", which usually means they will help you "fill in the blanks" on a purchase offer for their Client's property, but they cannot advise you what to fill most of those blanks with.In theory, all Agents must be fair and honest in their dealings with Buyers AND Sellers, BUT, they are limited by law in what they can reveal about their actual Client to other parties involved.Another point I would like to make is regarding comments about Agents not understanding the numbers.

Investment offers dual ability for both you and partner and tax benefits with no delays.
