IMHO, a 3/1/0 is a tougher property configuration to sell. 

That “creative” configuration was causing the leak.

The fund manager is paid on a % of how much capital he manages (various configurations but it is greatly steered/ impacted by fund size so I will leave it at that crude simplification) so COC is not much of a consideration on any 1 property as he is viewing the big numbers and taking a tiny % of a very big pie. 

There are a few caveats such as inheritance and dealing with partners or lenders, but overall as long as your attorney that you trust backs up your configuration and your CPA gives a thumbs up go with their recommendations .

This would keep the 3br/1b configuration and 1br will become a "master bed".

And again, as has been suggested, configuring so that the doors entering these bathrooms are in different areas of the rooms would not make this look strange. 

I've seen lots of semis with two exterior colors, two shingle colors, a half-new driveway, etc.I think the only way that you could split any other configuration of a duplex is by making it a condo and collecting HOA and having a condo corp... which for two units is absolutely ridiculous.

I believe you can link it to a CRM if you are using one and configure it to automatically add people from your CRM to a list of people who will receive your emails. 

Not sure how you would incorporate this into the ARV but interestingly, we were doing an inspection on one of our rentals today 3/1.5 and they had configured the kitchen in such a way there was no eating space.

Conventional lending wise buyer 2 will need to pay for the assignment through escrow in case since conventional cannot finance the assignment fee in this configuration / loan structure.Private money and non agency/non conventional products can finance assignment fee's or rearrange the assignment fee as a broker commission is one way around it such that conventional can "then," be allowed to finance the "assignment fee," but in this structure whats really happening is the assignment fee is being restructured into a broker commission which means the wholesaler buyer 1 better be RE licensed in the state of WA.So do your due dilligence and structure accordingly.
