Joe,
Commercial properties are usually valued based on their income. Commonly, this is based on a " cap rate" or capitalization rate:
Cap rate = annual NOI / purchase price
For yours, cap rate = 6.6% = $163,000/$2,500,000
That tells you what return your money would get if you paid case. That's equivalent to thinking about putting money into bank CD's.
From what I've seen, that's a pretty common cap rate. Maybe on the lower end, but not out of line with lots of other properties listed on places like loopnet.
Other ways to determine values are the comparable method (like is used for SFRs) and the replacement cost method. The income approach seems most common for commercial properties.
Now, does this make it a good deal? Personally, I think a 6.5% return is too low for this sort of investment. You could get 5% at a bank with zero risk. So, why would you sign up for all the hassle and risk for an extra 1.5%.
Of course, its not that simple. You can leverage your investment, and get a much higher cash-on-cash return, if the numbers work right.
For one thing, this is just a snapshot of the existing situation. Maybe the rents are low and can be raised. Maybe there is reason to believe there is significant future appreciation. On the other hand, maybe there is a major expense coming up or there is a lot of deferred maintenance.
I am not very familiar with retail expenses. Expenses on the apartments, though, will run you 45-50% of the rent, including vacancy allowance. The numbers you quote are 35% of the total rents ($87.6K / $252K). You might want to see details for each part of the deal. Ask for tax returns for the past several years. If expenses truly have been this low, I'd be concerned with deferred maintenance. At best, I think those expenses are optimistic.
I have heard recently its possible to get a 90% commercial loan. Getting a 90% 30 year loan at a decent rate may be a challenge. If you get the property at $2.3 mil, and get a 90%, 30 year loan at 8%, your annual payment is still $182,000. That means you're in the hole for $230,000 (down payment), plus closing costs (non-trivial on a commercial property) and losing $1500/month.
If you intend to open a single screen movie theater, you'll have to play to a niche audience. Multiplexes will take most of the business. Here in Denver, there are exactly two single screen theaters for the whole city. They both play offbeat films. Movie theaters are a very low margin and cut-throat business. If you mean live performances, its probably even worse. Most performance theaters require significant private and public contributions to stay afloat.
