I'd like to start getting into properties with more units and keep scaling up.

On the scale of mistakes you can make, $200 is on the low end.

A few reasons: turn key sellers take all the equity out up front and it is single family investing, not large multi.Large multi allows for efficiency and economies of scale and/or buying dozens of SFs within a few miles.

They took a 5 acre parcel I had purchased to build new transmission lines and re-conductor old lines in order to provide power from a new utility scale solar generating plant (solar farm) they had constructed.My attorney hired the appraiser with only 2-3 weeks prior to the date our expert witness and discovery production had to be turned in to the courts.The appraiser found very low comps in the area.

We have decide to scale up and look for a 60+ property in a c or low b class.

Which then means: you haven't been able to use the BRRRR strategy after all.I'm not saying turnkey properties can't get "10% yearly", but just that: it's too hard to SCALE those investments...

The snow is coming, so you have to have a plan and not rely on the kindness of strangers (or tenants).On DIY: I see some smaller scale landlords with a plow on their truck (and it may pencil out if you have enough units or be ideal if you have one anyway to do a long driveway or private road to your home).

Calculating the amount of eligibility used: Sliding scale method is used for all loans originating after 1/31/88. 

Will most certainly help you scale once you have a larger portfolio. - 2 of @Brandon Turner's books The Book on Rental Property Investing and The Book on Managing Rental Properties.

You will see they are investing in the strongest markets, have great broker networks / access to deals which is critical in a highly competitive market, can raise significant capital to take advantage of scale, more disciplined / conservative underwriting models, have simple well thought out business plans to increase the properties value, using fixed rate 10yr loans to take advantage of still incredibly low rates historically speaking and use more sophisticated tool sets to help understand how fluctuations in occupancy, rents, etc may impact their models.
