I don't trust them and it so much more reliable to take a few minutes and look at your real competition to set pricing. 

This property offers spacious townhouse like setting floor plans offering one, two and three-bedrooms.

I wonder if the change of density could off-set cost of underground enough to make it make sense.... 

I've actually had an investor give two of the properties back to me after religiously making his payments for 3 years on time but got a set of bad tenants and could not maintain the rentals. 

I would suggest making sure that you are following a set format/style of house each time you flip to systemize it more2.

Quote from @Travis Timmons: You'll likely find a bunch of folks here that set a pile of money on fire investing in Brandon's syndications over the past few years.

To set the stage, I'm owner of a short-term rental property in the Poconos in PA and we use a property management company for bookings, maintenance/cleaning, guest management, etc.This past weekend we had a guest booking but when the guests arrived Friday evening the house had no running water, though it had been running fine earlier in the day when the Property manager (PM) was at the house to give a final check and leave the welcome packet.

Both are almost set in stone.   

Are you working on any projects or targeting anything specific?

I'm not underestimating the work and unique set of challenges that come with it by any means.
