Get loan P/I monthly, put together a Capex plan for all of the current and future repairs. 

I am planning to buy properties out of State to fix&flip. 

They are not cheap and obviously require some kind of cellular plan, but I was able to get them to work using Mint mobile (you need a phone to activate the sim card on first, like an old iphone) Ive had 3 of these up watching a property in Cleveland, OH for well over a year, and Ive only had one issue where I needed to go check on the camera itself, (the plug for the solar panel came disconnected and just needed plugged back in) This camera in particular is nice because its actually 2 lenses that capture the full 180 degrees, so one cellular plan for "2" cameras.

I plan to use a DSCR loan.

At the same time, I am setting up a living trust for estate planning so that this property can be passed on to my hiers without any difficulty.

Make a plan that includes your goals, budget, who you want to buy from, what you're looking for, and your approach.

Ive also researched here about covering 5 units to 4 and some have referenced you can change a 5 unit to a 4 or have it in your plans and still get an approval...But others say no. 

Your best bet might be to check with Planning and Code.

Not the most ideal route, and we do plan on merging everything into one platform at some point, though that is a very complex project to undertake.

When I have something on the horizon I begin planning design right away.
