Property Criteria and Analysis

1. More cash flow from your property is an important factor in the building value.
2. In order to know the vale of your property follow this formula:  NOI (net operating income= the income after expenses) / Market cap rate.
3. Cash on Cash Return is how long does it take for the property to produce what you have invested. Is good to keep this as your main criteria and cap rate to compare one property with others. 
4. Gross Rent Multiplier (GRM) = Sale Price / Potential Gross Income   or   Sale Price = Gross Rent Multiplier x Potential Gross Income   is another way you could work out the relative price of the property. Note that the GRM can be deceiving as from property to property it may be much different the vacancy rate and taxes, this system of comparing and selecting investment properties only when the expenses are uniform across properties.
5. Observe the trends of what people are doing is the key to find new opportunities.
6. Check the demoghraphics of the area you are willing to buy a property. see  http://www.freedemographics.com/
