Sell the properties.You mentioned having difficulty managing the properties as is.

I've been sending people to a Realtor/property manager in Sacramento.

@Luke Spencer I am not on the management side but I can tell you it took 2+ years to fill 300 units at one of our facilities and the other just hit 300 units in 12/13 months so it really depends on the demographics, and local housing market trend, the more people moving in and out the higher the demand for storage.I think if you're looking at a saturated market then the upfront cash to turn the warehouse into self storage is not a good idea but then again, maybe those operators are on back roads ( low visibility ) and don't push google ads well.

The only other question I would suggest is that you do engage a property management company to review your quad and review your monthly financials.

These properties are often easier and more affordable to manage.

The place where you can add value with no money is a situation like: you find project A, it is a 120k purchase and it should need 80k rehab but you can get rehab done for 65k cause you can do some of the work and you know how to save on materials and you can manage the rehab. 

The property offered a balanced investment opportunity—enough to significantly enhance its value through renovations, yet manageable in scope and cost.

Your project manager should know plenty of guys- delegate this to them3.

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

5unit is probably manageable.  20 unit is work I would think.
