There would potentially be some weight issues with the 2nd+ floors of some shopping malls, depending on what the potential tenant wants to store in the upstairs unit. 

Taxes : Taxes have been a brewing crisis nationwide for sometime, Chicago is another prime example of a major municipality struggling under high debt load.

If you enter a neighborhood and you immediately lock all doors from the inside, and check to make sure your gun is loaded, you are in class D no doubt.On the other hand, most class A+ neighborhoods as you drive through you cannot see the houses from the street. 

Adding mass to the walls works wonders—attach Mass Loaded Vinyl (MLV) to the shared wall, then cover it with a layer of 5/8” drywall using Green Glue soundproofing compound for extra noise-blocking power.

The first applicant will eventually get tired of his free-loading friends and problems will ensue.

Ask for its breed, weight, and name, and have them attach a picture.- Make the application part of the lease, with the stipulation that if they've lied in the application or in the lease, they can be evicted.- Tell them they have to provide documentation of the animals service / emotional support (as allowed by your local ordinances), and that they have to provide documentation that the animal is current with its inoculations, etc. as well as its local license before you'll permit the animal in the unit.- Tell them they'll have to provide you with a copy of their renter's insurance naming you as additional named insured, with a minimum of (I use $300,000) liability insurance, also before they move into the unit.It's not perfect, but it's a start toward a tenant transparency.

Quote from @Bob Dole: All,Apologies for the newb question, but I just heard about cost segregation and have been reading up about it online.My understanding is this (and please correct me where I'm wrong):Pros: -accelerate depreciation, front load (vs. just a straight line over 39 years) -save money on taxes because of the depreciationCons: -if I sell the property, the recapture will be larger -not recommended if you flip propertiesSo hypothetical situation:-Majority of our income is W2 based, let's say it's $500k-Net income from commercial rental is $100k-Income from dividends and interests is $100k-Both of us are full time W2, so non-prof real estate (but this can change  -- please see below)So we're hypothetically grossing $700k a year. 

Some items might hold more weight than others, but you guys should sort through that together.You also might just do the partnership deal by deal - sometimes jumping into a partnership before you have officially worked together is NOT the best idea...

For instance, in my private lending, I dont really give a numerical credit score much weight, but I absolutely look at the composition and history of the individual tradelines on a report if the borrower is a smaller outfit, such as a single member LLC or similar solopreneur-type operator.

I have a wife and 3 kids and the weight of their futures on my back.
