I'm having to make some assumptions because there is missing info in your post, but it sounds like the flex space doesn't have a separate door to the exterior.

For anyone else that responds, please refrain from assumptions, allegations or opinions.

@Jacob NevarezRecommend you figure out the property Class you want to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

Here's some copy & paste advice we hope you find useful:----------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

You could figure out roughly what range the properties you would be targeting would cost and use your own assumptions to come up with something similar.

Personally, if I see a property that went back on the market after being under contract, my first assumption is, 'What did the buyer find wrong with it?'

Again, others might feel differently here.3) property level due diligence: (takes seconds to weeks per deal): here is where I drill in with the low-level details.a) pro forma popping: I examine all the assumptions, and see if they are overoptimistic or not.

A lot of your assumptions are quite optimistic, very little room for the inevitable headwinds. 

If you acquire the property in the middle of November(Assumption of November 15th), you will need to clock in about 2 hours a day.You might be able to log in a lot of the hours as you furnish and rehab the property leaving you with 30-minutes / 1 hour towards each guest check in / check out.It is do-able but obviously, sometimes, the more time the better.
