Title companies need to insist everyone use a trusted notary, not just any random remote notary, and take additional steps for any remote closings such as holding funds in escrow after any remote closing until they can 100% verify that they’re not going to be wired to a scammer overseas. 

Multifamily properties at a discount are hard to come by, especially if you are looking in the nicer parts of town. 

I have not read the book but I have done many sub 2's over the decades and for us it was just a standard purchase contract and when it says additional terms we just described that we were taking title subject to the existing debt or which debt would remain on title.

Additionally, could anyone recommend the best platform for listing STR and MTR properties tailored to traveling nurses in the Birmingham area?

I have homeowner's/hazard insurance on the property through my mortgage, but I do not have any additional landlord insurance or other coverages.  

Addition costs for staging.  

I am a first time real estate investor looking the following property : https://www.redfin.com/OR/Forest-Grove/2418-Cedar-Cir-97116/...its a pretty large duplex in Forest Grove OR,  the trick is though, its on a lot zoned for a 4 plex so I am lookinginto house hacking, converting into a triplex, then living in one unit while renting out the remaining two unitsThe left garage has been converted to living space, with a living room, half bath, a laundry room with a sink and some counters/cupboards and a bedroom, it is a part of what was an existing 3bd unitIf I were to acquire the asset, I would first attempt to convert that space into its own unit The line items as I see (be in mind, I am totally new to this) would be to >put up dry wall where the door to the rest of the house is,>add a shower to the half bathroom >install a water heater in the adjacent 3bd unit> install a kitchen in the laundry room, (stove , oven , sink, counter space)>add a shower to the half bath Assuming I can convert it to a 3plex, I could at-least cash flow on my investment after I leave My plan would be to put minimum down payment of 3.5% (FHA loan) that way I can have a decent amount of capital free to do the renovationsThe only concern is when I crunch the numbers to get my ROI, I have no idea how much its going to cost to convert the additional living space to a third unitAny experienced investors here know how I can estimate this before I try to make an offer?

I agree in that the easiest way to go about this is to sit him down and in your best manner state that there are inconsistencies and you'd like additional documentation as you do have an obligation to uphold (in keeping the current tenants safe and ensuring this person is who they say they are).

The additional income from the ADUs will easily cover the cost of the loan and produce really solid cashflow.

I do want to sell a house at discount.
