To sell or not....

[Jason Krawitz]

I received an attractive cash offer to buy my one and only paid for rental property. I'm relatively new to the real-estate investing world and am struggling to mentally calculate and quantify the offer in comparison to the expected future cash-flow + increase in value of the property. Are there any calculators out there that can help me analyze this objectively? 

To put it in different terms let me ask this. If someone offered you, for example, 115% of your home's value to buy one of your units, what factors would you consider in regards to holding the property or selling it for the offer?
