I know i need to start looking more into tax strategies.I understand that save/buy is a (relatively) slow  way to expand.. but i'm also not looking for a "Boom"I'd be hard-pressed to refi... i've decent  rates and for now i'm looking at cashflow until i'm not dependant on my W2 job ( i think  that at 7 units i could "get by"..barely) then i can  move towards being more concerned on long term wealth/retirement/equityThe rentals have their own business account that i do not dip into** I do not pay myself rent, BUT the business account does pay my personal gas/electric.from my W2 earnings i spend about $1300/mo on everything ( from car insurance to eating out), rest is savedany new downpayments are a mix of business account and savingsWith the 5 total units ( 4 rented; 1 personal use)  I "Cashflow" about  $1K/mobut that number does not account for any CapEx.What might you change/suggest about my strategy?

I also leave myself about $1000 per month to account for varying expenses such as groceries, gas, gym memberships, doctors appointments, and of course other varying costs that come along with being a single dad!

Be prepared to have a large breaker box OR gas hookup.

While my 44 year old gas furnace in a rental runs good the management company had a furnace guy say it is in bad shape.

And of course working smoke alarms (and if gas, carbon monoxide detectors).  

Some things you can test for without utilities on, i.e. pressure testing gas lines and plumbing lines.  

Broker is suggesting purchasing NNN lease single tenant properties - such as Wendy's, Starbucks, auto parts, gas station, etc. 

I had an older building similar to what you are describing and the electric from the common area, gas, water, and lawn care, quickly ate up a significant portion of my cash flow.

Even a 15-year-old Honda or Toyota can be purchased cheap, doesn't eat much gas, and should last you for many, many years.4.

I need a ton of help but mostly conservative costs projection to build a  5 home subdivision, average lot 1.2 acres, longest distance to run electrical wires, water lines, gas lines, sewer lines would be 1200 feet, install a double road, fire hydrant, 50-75’ driveway from road to each house, 5 street lights, cable.
