Concrete cost is an exposure since we can’t contract ahead.  

I’ve noticed that my confidence grows with every conversation I have with experienced real estate investors, and even more so each time I take a concrete step forward.I'm a strong advocate for personal growth and development, and it's great to see that you also view it as essential to success in investing.

The basement is full, concrete walls that are very straight.  

We even dig foundations and pour concrete when it's below 0.

For example, if someone has 3 listings, they'll be paying around $50 each but if someone comes on with 50 they may be paying like $25 (these are not concrete numbers) they also have add ons like dynamic pricing and smart locks which are additional. 

I typically only run numbers based on concrete things that I know of right now.

Something to look into, nonetheless not enough info to give you a concrete response.

I don't know the cause of this problem, but in other areas of this floor you can feel low spots where the concrete slab was not completely level before the flooring was laid.

This is usually the financials they use from their Accounting system and not concrete numbers but allows you to see how they are doing.
