Is it time to sell 3-unit property

[Matthew Catanzariti]

I have a 3 unit I purchased in 2017 for 575k in todays market I’ve been offered 950k for the property. Within the next couple of years I’ll have to do some pretty big projects to the house including siding, some windows and redo one of the units. 
Am I crazy for thinking about selling? I know people on here say hold hold hold but it seems like selling may be a good idea.
