If your hvac contractor tries to sell you a new furnace by telling you it’s more efficient and over one you may save money via energy savings, less repairs, etc that’s fair.

This makes it more efficient to do the pay check parking strategy or velocity banking (other market buzz words are available as well). 

Is there a way to efficiently estimate the ARV of the property without having to pay contractors and/or appraisers to look it over?

I don’t know if Jerryll’s method is the only way to obtain leads efficiently, but I hope everyone else beliefs him so I can stop getting solicitations! 

Time, Interest, and Energy.  

It can be done if you have the energy and drive to push forward.

@Don Konipol not out of the air, based on my own rental and a few hundred others we've done at Net Energy in 8 states.

Outside of jeopardizing a current property I own, the spread on this can't be worth the time or energy. 

The reason I ask is that studios compete with hotels and hotels are efficient.  

There is a large demand for efficient distribution and storage of goods, thus many investors are looking for ways to increase their financial performance while continuing to remain competitive in the market.
