I think that's what you'll need to get for proof of excess noise.

Water intrusion into any part of any physical structure on the Property; leaks from or in any appliance, pipe, slab or roof; standing water, drainage, flooding, underground water, moisture, water-related soil settling or slippage, on or affecting the Property?

Unless you've got something unusual <$500.I'd be looking for stuff like:1) Major CapEx - Life of roofs and siding and paving and plumbing2) Moisture invasion ANYWHERE since this gets more expensive the longer you wait3) Making sure stuff (like remodels and wiring) is up to code. 

( That can include large unexpected repairs, for example, like finding out you’ll need a new HVAC system or a new roof, which can cost upwards of $500k plus).In addition, some of the investors who expressed an interest will end up backing out, and having an excess or reserve will help fill in the amount you lost.

A problem would be if she opposed it & refused to let you get started because she was too scared, or she wouldn't go for it because she has a spending problem and wants all excess cash for immediate consumption rather than investing. 

The inspector also noted that there is moisture in the walls detected by his tool. 

You take the 245,000 and pay off the old loan of 150,000. so 245,000 - 150,000 = 95,000.You take that excess 95,000 and put it towards your next down payment on a new property.And even with that new loan of 245,000 you still cash flow from the rents. 

Can this be rolled over for multiple years if the cost of rehab is in excess of the rent?

Might also be wise to target the younger generation before they get too far into a career or college path.Household income must be 3 times the “Monthly Operation Payment”.Create unique opportunities to create income from excess space in a property (vacation/air bnb, temp housing for travel nurse, students, etc.)Residents may choose to use roommates to meet this requirement.Pet owners buy all the flooring instead of a pet deposit.

But I want to do something with my excess funds and real estate seems to make sense.
