Since merging my company with Southern Impression homes 2 years ago, we have made a lot of strides in growing our PM department and client systems.

@Albert Hepp the flawed logic your using to state there must be some conspiratorial aspect to commissions because commissions are all but uniformed over 2%.....We can apply that exact flawed logic to Apples at grocery stores and say since apples, at every grocery store are uniformed at a price over $0.10 a piece, it "must be a conspiracy"........Take off the tinfoil hat. 

Location. 25 minutes to beach, 40 minutes to Florence, 15 minutes to Pisa, 60 miles to snow skiing.  10 minutes to Home Depot style store, etc.  

You can find everything you need to know in a grocery store to make Pumpkin spice loaf with almond praline dessert, too.

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

I would venture to say very few landlords correctly hold their deposits based on local landlord/tenant law but as long as the money doesn't walk away and is not wrongly withheld from tenants its highly unlikely wrongfully storing the funds will become problematic.

I paid off 19 units last year - 17 apts, a store and a house.

Originally posted by @Mark Whittlesey: I would get a UPS Store (or similar) box instead of a PO Box.It costs more but is much more flexible (is an actual physical address, can receive UPS and FedEx etc.)I had a PO Box for a while and got rid of it for exactly those reasons. 

The storage closet is storing a shower head, a toilet, and whatever else you threw in there.

At a minimum,  you should understand what the current zoning is and what restrictions there are.As the post above mentioned reaching out or going in person to speak with the planning and zoning department will be very helpful.
