I think you're looking into "cap rate" a little too much :-) I would focus less on cap rate.
"..is it better to buy below the average cap rate for the market, or above the cap rate for the given market?"
This one is easy. I'm assuming everything is held constant, all numbers are verified, the properties are the same quality, in the same quality market. When you buy below market cap rate you pay more than asking price. If there is good reason for this then the price you pay is the new market price for that property (i.e. you set a new cap rate). When you buy above market cap rate you pay less than asking price. A good reason for this could be you just got yourself a good deal or it's a declining market.
"I can even likely increase the NOI which will increase the Cap rate more. Yet people are telling me this too high of a cap rate and I should be hesitant. I don't understand it, can someone help..."
You should abandon this concept of making money by purchasing a property and "increasing cap rate". As you stated, increasing NOI will increase cap rate but then people say "too high a cap rate" is a bad thing. Hmmm… seems contradictory, isn't it? If you buy at 10CAP and pull out your tricks and increase cap rate to 15CAP, I'm guessing people would say it's a good thing, right? But what if you were able to increase cap rate to 25CAP? Would people say it's a bad thing because it's "too high a cap rate"? Where is the threshold where you go from good to bad? 19CAP? 21CAP? What's the formula to determine "too high a cap rate"?
This is the reason you should forget the concept of "increasing your cap rate". You already have the answer. You purchase a property and make it your goal to increase NOI. The higher the NOI the higher the value of the property. Who cares what cap rate does. No one is going to complain about your NOI being too high (i.e. "too high an NOI").
"On the flip side, with interest rates so low, does this also mean there is a risk for the value to decrease a bit if rates rise significantly. For example, if this $500k purchase price goes down to $475 market value with increased interest rates, then the cap rate increases and the investment was a poor choice."
Although they’re not strongly correlated, there is enough data to show that cap rate tracks the movement of interest rate (some say cap rate tracks the movement of 10-year TBill yield which influences interest rates in general). In turn, interest rates movements directly affect investors’ required ROR (i.e. rate or return) in that higher interest rates lead to increases in investors’ required rate of return and therefore drive down valuation of asset in general (including real estate). So I agree that should rates rise real estate values would trend down. At least this is the theory in general but know that we’re dealing with real estate where everything is local so there are of exceptions.
Your example of $500k at purchase and $475 current value (i.e. buying at lower cap rate) is not necessarily a poor choice. It’s not a poor choice if it was planned from the beginning. In the current environment of low interest rates and low cap rates, many conservative investors build into their underwriting to buy at lower cap and sell at higher cap. And, yep they still make money.
I also agree with another poster that there is something more about a property for sale at 10CAP when the prevailing market is at 7CAP. WHY would anyone sell below market when he can easily get market rate? Is he ignorant? Is he generous? Or maybe there is something about the property you do not know about?
