Own 2 properties (a duplex and a 4 plex).

It seems like a solid basic house : slab, block walls, single story, post-lead paint construction, and town water (wells are a Pita).

My fiance and I are looking for a multi-family home (duplex-quadplex) where we can live in one unit and rent out the rest. 

This one irks me a bit because the paint on the walls is actually builder primer and they required us to wash all walls prior to move out.

Our landlord has indicated that he is looking to list the duplex we have been renting for 2 years +. 

It is a duplex renting out at $800/month and has a zillow value of just under $50,000 in Cleveland, OH.  

I am very very new to real estate investing (been listening to a couple of episodes of bigger pockets over youtube).My main goal is to start building a second income, and buy more real-estate assets over time. i was think about buying a single/duplex with a friend together as my first investment will be a good start for me. i live in Israel. and real-estate here is very expensive here and its require a big investment just for my first asset, also the return rates are very very low.so my question is what do i need to do .- Do i need a back account in the US.

One deal is a quadruplex and a duplex, the other is two quadruplexes and a duplex. 

so a triplex/duplex only requires the same review as a Single Family home.So, I'm just building an excel spreadsheet with best/worst case budget #'s for each step in the process,  get an approved set of plans and then I'm going to shop it to 3-4 builders I already like in my area.   

A scope of work provided with an application is clearly an estimate as you can't see behind the walls/ know to the dollar what things will cost etc. 2) do all HMLs require inspections and appraisals (therefore you must keep these contingencies and make your offer less attractive vs cash buyers)?
