@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.

Depending on the actual age of the property, at least some level of deferred maintenance is not uncommon.

Depending on your exact situation, you could likely get something closer to 7% and make these numbers work a little better.  

It depends. all you talked about was the property but financing is more about the borrower, their experience, their credit, the cash available etc.

If a landlord plans to hold the property for a while, we always recommend an annual lease, ending to align with the summer leading lesson, or staggered with their other leases depending on the situation.  

Best I can tell all in all we about 3X cash on cash over 5 years.infil lots depending on lot we could double our money in 9 to 12 months cash on cash.. so on and so forth.

Depending on how close you are to Philadelphia you can really manage the property yourself as many Jersey neighborhoods are even closer to philly than some philly neighborhoods.

Depending on your state, many have local lenders that will go up to 100% LTV. 

Patio door prices can depend on the Model of Patio door you are looking for, for a standard 60x80 in white it will cost $1900.00 colors can be added, and for a patio door 72x80 the cost will be $2100.00 Outswing for a 60x80 will cost $2600.00 installed, and for an outswing 72x80 it will cost $2700.00 installed outswing with Grills for a 60x80 costs $1860.00, and an outswing 72x80 will cost $2300.00 installed.You also add blinds to all sliding and outswing patio doors for an additional charge.

But it just depends on your risk threshold and how much you're looking to spend.
