Commercial real estate is completely different animal than residential. Loop.net is a popular site where you can review commercial deals. Outside of that you need to find pocket listings and build relationships with brokers and Realtors that list commercial properties. You can also go to http://www.Listsource.com and pull criteria to send out a mailer to a very targeted list of owners.

100+ unit Apartment Buildings. With the ever increasing mortgage lending guidelines disqualifying an estimated 80+ percent of the U.S. population, America is fast becoming a renter nation. This is why guys like Robert Kiyosaki, Grant Cardone, etc., are bullish on apartments. Ridiculous financing can be negotiated with Fannie Mae on non-recourse loans to maximize leverage and cash flow. With the right properties, cost segregation can immediately increase cash flow and ROI. 100+ unit apartment buildings can offer a great return on a collateralized investment and fantastic tax advantages. This is why our current posture is looking solely for these types of properties.

I've been investing in residential and commercial real estate for over 10yrs and have learned from a lot of decisions along the way. Certainly depends on the type of property, type of investment, and structure of the transaction. For example the answer would be very different between a SFR and a 200 unit apartment complex. I always start with the macro - what is driving people to rent property in that part of the city. Will the reasons people are renting there continue to support future rentals and future rental increases (jobs, development rules, pricing, etc.) If I like what I see for that city and that part of the city from a macro perspective, I look at the economics of the property itself (price per unit in relation to deferred maintenance, does the NOI pencil out to what I need it to be, is there upside in rents or utility bill backs or appreciation, am I buying at a discount due to deferred maintenance or lease risks, etc.) Then I look at the structure of the deal itself - if I am leading the investment and have LPs, what is the rate of return for everyone involved. What is the holding period, plan to sell vs. 1031 exchange, etc. Some of the areas where there can be difficulty is on deferred maintenance that a seller is unwilling to compensate you for (negotiation techniques are your friend here). Issues with the leases (some might be easy to overcome and others may not be). Financing (will a bank want to own that type of property in that city).
