A money market account seems like a good possibility but we are unsure about the accessibility for when we need to pull it out. 

In fact, I'd double-down and see if you can get your bank to offer a first lien HELOC on the property you own so you can have even more access to funds there.Amortized interest is inefficient, and favors the bank.

One of my prior deals my agent offered access to an exclusive venue that he is a member of.

Now I pay one price for a user monthly and that is it and get access to everything.I like the new set up a lot but can understand why you do not.

@Christy Crivellaro it sounds like you just need to get access to mls and start running numbers daily.

But I make sure that I have the following in place from contracts: (1) I get the late fees (2) no upcharged on repairs, (3) i get to see the contractors invoice, (4) i get access to all data. 

Values depend on location/gulf access, bridges, water/sewer assessments paid already, etc. 

Will they transfer over records and system access as part of LOI?

Develop a "New" investor info module, they have to go through to gain Post access. 

Ideally, create a separate gate to be used just by the ADU tenant to access their unit.Natural light: ADUs are small and one of the best ways to make these spaces feel bigger is to ensure lots of natural light is flowing into the unit.
