As a general rule, each entity that files a separate tax return (partnership, s-corp, c-corp, etc) will need its own QBO subscription.

The LLC was used in an active business for separation of the active business from my other businesses, rental for one.

Doing a short term rental in a separated area that has its own designated, kitchenette and bathroom, would likely give you better returns and less headache.

Also, are you doing separate loans, or one loan covering both properties?

Then separately I calculated the appreciation against each home value observation in the ZHVI dataset against its value 10 years earlier for each month.

However, they all require separate applications to even get an estimate.

I do own two triplexes in Scranton, and I will say the one issue is that you are going to be taking care of the utilities normally if they are not on separate meters, which could take a good amount of money away from your overall cash flow. 

These two concepts are separate from each other.

However (to go into detail requires a separate post), that's not quite the correct course either.

My fiance has orders to San Diego, and I will be separating and moving with her.
