You would be better served to collect quotes from a handful of foundation specialists then choose one.As for costs, it will be dependant on many factors: type of foundation; type of soil/rock; depth of underpinning / ease of soil removal; and your location.

I actually bid up the price between myself and the auto bid software to what I felt was the rock bottom lowest they would accept, and they did!

That being said come August/September landlords facing vacancy are forced in between a rock and a hard place.

I think your strategy is still rock solid.

You may get a draw against future commissions, but most brokers are one-man bands.

goal  = build portfolio = option Bgoal = 80% or better equity = option Aas you mentioned, the cash flow is higher, not lower, by choosing option B with the savings reinvestedoption A seems to trump option B (but I personally would do option B and maintain the proper reserves)

BP - I live in Houston, TX, and unless you have been living under a rock, you have heard about widespread flooding from Hurricane Harvey.  

We'll probably sell the "A" and buy the "B" and "C" deals.

I like to invest in B and above class areas.

There's a narrow band in the middle with good rates that you typically see advertised, then a "high balance" range where they aren't so good, then a "jumbo" range where they get better again (sometimes we find ways to shove "high balance" loans into "jumbo" for that reason).
