I'm not an accountant, and I'm not a lawyer, but in my opinion, having one LLC per property can be considered overkill, unless there's a lot of equity in each property. 

However for ongoing management, a full service property management company would be an overkill.

It's probably overkill unless you have at least 10+ doors to manage. 

A new LLC for every property is probably overkill.

@Malinda GibbonsYou need one bank account for each entity for operations and an escrow account if you take security depositsIn your accounting system you can classify the assets and run p&l for each oneIt’s way overkill to have that many accountsYou are just adding work for your business which takes time away from you doing more for your business

(basically quickbooks lite.) it’s overkill for personal finance and 13 doors.

@Rob Sawyer While you can buy a list from listsource.com this may be overkill.  

Sounds like it might be a little overkill though.

This year taxes there overkill even Shaker Hts - notoriously highest in NE Ohio.No POS in South Euclid, only vacant houses inspection.

Note.. due to the circumstance that indeed good roofers do not want to do anything unless you change entire roof... but frankly speaking this is overkill..In fact i observed similar overkill in other professions.. in electrical, hvac you name it...... all through the back of my warm sit...simply by watching tons of youtube videos and courses...The real danger in investing into commercial real estate or any other real estate is not knowing inner details of the trades.........
