I just signed up for BP pro membership and have been enjoying the rental calculator feature.

I'm having trouble determining what the extra value of certain features is.

The two main reasons I would not consider taking a withdrawal or loan from a retirement account are: - As others have mentioned, this feature of the CARES ACT allows a withdrawal or loan as long as you acknowledge that you have been financially impacted by the virus.

I actually wouldn't give them the option, just advertize it with that as part of the package and a selling feature.

The home was less than 10 years old and had very nice features that would make it a desirable rental and retail home.
