Two of the three houses she wants to sell have tenants so she is kind of forced to sell to an investor/wholesaler unless she wants to wait til next year when the leases are up.

I follow BP to remind myself of where I came from with Duplexes and Houses in S.

I agree with @Caleb Brown and @Lynn McGeeinWhen I bought my first house in 2018 I had the same problems.

Starting from the basic, a house has laundry and a refrigerator and a place to eat, to be with your family.

@Elan Adler - I think the reason you are not getting much in the way of responses is that you will not find a house for $250k here that rents for 2k. 

Same process anytime you sell a house that is leased out.

If that number is greater than the purchase price of the house, then I would consider buying the property after looking at other factors (location, condition, neighborhood, zoning, etc).In other words, 6 straight months of rent should pay for the house. 

Congrats on serial house hacking!! 

You can do all this without a lawyer, but mind you, expect your house to be trashed. 

2) Does old carpet bring the house value down?
