Marta Frey I have had Texas National Bank out of Jacksonville Texas do a 30 year as well as a 20 year variable.

I mean there are hundreds of variables here.

This is a common question nowadays and a tough one to answer without all the variables.

Cap Rate is a measure of the ratio between the cash flow produced by a property and its capital cost (the original price paid to own the asset) or alternatively its current market value.The rate is calculated in a simple fashion as follows:annual cash flow / cost (or value) = Cap Rate For example, if a building is purchased for $1,000,000 and it produces $100,000 in positive net cash flow during one year, then:$100,000 / $1,000,000 = 0.10 or 10% The properties Cap Rate is ten percent.NOTE: Positive net cash flow = The amount left over after all fixed costs and variable costs are subtracted from gross lease income, however before debt service is subtracted.

Interest rates are a little bit higher than residential and typically they are only locked on for 3-7 years or can be a variable rate from the beginning.

Once that's done, another scan of email will usually result in a few other things to handle, which runs the gamut of so many variables that I literally don't do the same thing every day.  

Each of these variables will dramatically change the advice I give the individual asking me this question.

We do have a variable rate HELOC on this property that has increased quite a bit in recent years.

Typically between 2-4 points and 8-12 points but extremely variable on a variety of factors

When using a HELOC with a variable rate, when you take out a loan against your credit line, are you "locked in" to that rate for the entire amount you have to pay back on the amount of money you took out, OR do fluctuations in the prime rate also apply to money you've already taken out?
