you don't need off market land. most land is listed is fine. it's a buyer's market for land in most markets which means more than a 6 month supply. practice underwriting the deals and making offers, find deals they may do owner financing, etc on. 

As an owner is it better to a) install mini splits or  b) make renter supply their own air conditioner.

Low supply leads to rising prices.  

However, multi-family deals seem to be expensive, overdeveloped and in short supply on the MLS. 

Two of my guys, a container full of tools, supplies and materials, a tent to sleep in.

You cant compare between the two.The truth is residential is good location and has more demand than supply always appreciate over ten years. 

I get the money printing, but the lack of supply was more detrimental to prices as was the supply chain more detrimental to inflation than anything else. 

A few years ago a MF boom started (that is still going), and I realized my older units in cut up old victorians weren't going to cut it against new supply.

That's true of every market now, I suppose, with interest rates and supply problems, until either prices go down or rents go up.
