The entire rear addition is unstable and needs to be removed/replaced  (about an 8-foot deep wood staircase with landings and entrances to each of the 4 units, plus extra space for ~60 SF per unit).

The entrance is now a little more awkward to get to.

Then, how to build an investment plan of entrance and exit strategies, that are linked together (steps), and form your plan.Wanting to "buy three holds, and flip 2 properties a year" isn't a plan.  

congrats on your first deal. i may be close to closing on my first deal soon. as a master investor you should have about 7 entrance strategies (give or take?)

If that is the case, I would NOT convert it ... instead, you could look to add a "mother in law suite", casita, ADU, or whatever you want to call it with its own separate entrance and maybe shared access to laundry that you could rent out, but still keep it a single family.

A 2 story home with separate entrances (Possibly built so 15+ years convert it into a single home with upstairs/downstairs)Basically, I am asking if this situation would work.Sell current home, and build a new home in that half of the property would be rented out and I would live in the other half while being the landlord.

I personally worked with one and that was an easy entrance into out of state investing and setting up your team.

I am currently shopping around for a Camara Security system for my 10unit apartment complex, located in Grandview, MO.I am wanting to be able to monitor all exterior corners along with entrances and common areas in the interior - it would be about a total of 15 camaras. 

Touching up the front door and mailbox is cheap and easy way to make the entrance clean.

There are still some good multi-families in Tacoma, and plenty of properties where you could add a MIL / ADU by finishing out a basement with its own entrance.
