If ifs commercial multifamily you’d use a cap rate

What and Why would an investor want to change a cap rate vs increasing their value? 

Is it possible to put a cap on the mayor's salary and income?

Why not put in your lease that if a tenant turns before twelve months from signing there is no lease up fee or have a cap on lease up fees charged per year.

When I questioned him as to why, he said that if it starts to drip, a lazy tenant could put a cap on the bottom and cause the tank to explode.

Are you thinking a cap rate predicts profitability?

Remember that a cap rate is only one tool to help you determine if you want to look further at a deal.  

I’m not sure I completely understand what your asking but I’ll try to answer.Let’s say you buy a property for $100,000 with a cap rate of 10% and you get a mortgage at the rate of 6%.

To me this looks like an NOI of around $10,740 indicating a cap rate of about 31%.

One of the biggest trends I have discovered so far by studying sold property data has been a cap rate of 3.5-4.5% (now this has gross assumptions such as a 45-50% operating expense structure--and no, when I put down an offer I will not use this, I will actually do a valuation of capex using lifeyears although repairs I'm still working on....) .
