Figured that would be enough second, you have cash flow, ~250 bucks a month if you buy rightyou get the tax benefits of mortgage interest deduction and depreciationand you have 100% of your funds back in your pocket. this process doesn't scale well, but it's incredible lucrative and efficient. also, the details matter here so those numbers are subject to vary, this example is pretty much exactly what I do though. 

I'm looking to start scaling up and acquiring faster (better!)

I was speaking with a new RE attorney (well, not new to RE, he's been at it 30+ years, just new to me) the other day who asked if I was going to scale up to multiple projects at once to achieve economies of scale.My answer was that I would do that in year two or three.

Purchase price: $599,000 Cash invested: $60,000 FHA 3.5% down with a refinance....Personal residence which where I will rent out the entire house when I scale up eventually.

Can or should I use it to negotiate a better price or is it to only scale the sellers motivation?

He gets the benefits of scale and does not need to lear on the job as much. 

I would look for cash flowing properties in the market that I’m investing in.Or I would just scale my portfolio into a much larger units or properties.

Then scale up to allow the business to run itself and allow my wife and I to travel with our kids to see this great country.
