Cap Ex for Townhouses with HOAs?

[Brandon Boogren]

What percentage do you put towards Cap Ex when purchasing a townhouse for a rental? I am practicing analyzing deals with the BP rental property calculator. I found a townhouse that cashflows ~$200/mo if I remove Cap Ex (I currently have it at 10%). 

The HOA says it includes:

• Sanitation, Snow/Lawn Care, Outside Maintenance, Water/Sewer, Professional Management

Should I treat a townhouse with HOAs the same as a single-family home when it comes to Cap Ex? Or does the HOA typically account/cover for big expenses within their HOA fee?

Any thoughts/advice would be greatly appreciated!
