Ok, so we're discussing "Full Retail" and whether or not we should be paying it for investment properties - but how do you determine what full retail value actually is?
In my mind (and I believe this is a common expression) something is worth what someone will pay for it. For the sake of argument, if a property has been on the MLS for a year at $100,000, and you come in and buy it for $75,000, do you think you're paying $25,000 under full retail? I would argue that $75,000 is the actual value, even if the identical house across the street sold for $100,000, 366 days earlier.
Is it just a matter of casting a wider net? Looking at an entire neighborhood, zip code, or county for comps? Even then, we talk all the time about the difference a couple of streets can make in the value of a property. That's true in areas large and small.
Is there a REI formula for what is considered full retail or full market value? Especially in lower sales volume areas (that might not have more than a handful of multi-family properties at any given time?)
I think a lot of great points have been made in this thread, and it definitely represents a great cross-section of great investors, but it's interesting to note how the different markets have influenced the investors. i.e. @Account Closed's 'buy for appreciation, cashflow is too speculative' mentality (can't get much more Hawaii than that!) and @Ben Leybovich's much more conservative mentality (because if you buy below market value, it cashflows well, and then appreciates, you'll be able to survive when disaster strikes.)
As an aside: Ben - I've looked through your articles/posts, but you write so much I can't find what I'm looking for (or maybe I'm just a complete idiot) - can you point me towards the correct way to calculate IRR? Any tips for a new guy on estimating appreciation? For all my estimates I just assume it won't appreciate at all, and make sure the numbers still work before considering offers.
