How do you find a Commercial Industrial Property BRRRRs ARV?

[Arsen Sapsa]

Hi everyone, im very familiar with finding the arv of residential properties based on comps. However i cant seem to figure out how to find the value of a industrial property after it has been rehabbed and rented out.

Lets say i bought a warehouse for $500,000 using a hard money loan. Spent $50,000 fixing it up and rented it out to 100% occupancy. Rental income is say $5,000/mo. So im all into this industrial warehouse for say $550,000. Now that its been rented out and fixed up when i go to do a cash out refi how do they find the value of the property? I would like to pull 100% of my money out, just struggling to understand how they find the value when i cash out refi. 

Would GREATLY appreciate any feedback.

Thanks!
