If so, you can test each unit separately, as it seems obvious that the first floor leak would be from the second floor, but water is a tricky situation.For the roof, I would certainly get several groups out to let them diagnose the issue and bid the resolution.  

Quote from @Ryan Prange: You don't need separate bank accounts unless they are under LLCs, then you will need a separate bank account for each LLC.

It seems that getting an ADU would be tough to get in Montgomery county if renting a basement (with separate kitchen).

Separately, there are tons of older extended stay hotels in all the major growth cities with people living in them paying (fairly high) monthly rates due to convenience or lack of qualification for typical rentals.

But the liberal legislators like to camouflage this constitutional taking by appealing to the emotions of the public by using the term "eviction." 

One more tip – people remember stories that trigger their emotions.

MLS in the UK - negotaiated over a few weeks and tried not to get emotional on the purchase.

I've come across a property with a basement which i can turn into a separate unit.

You don't even need an LLC for a rental property, especially if there is a mortgage on it.Make sure you have the correct type of insurance as your number 1 priority.My partnerships have a separate tax return and it issues a K1 for my personal return.
