I am looking into buying a duplex in Hyatt Park and wanted to get some advice on what contractors/suppliers I could contact that have investor friendly pricing for kitchen cabinets, countertops, and bathroom vanities.

We turned the 4 bedroom, 5 bathroom property into a 6 bedroom, 7 bathroom property, plus a caretaker's apartment.  

He went back inside and got another photo of the bathroom.

I am ready and will be starting with property number one sometime, hopefully, quarter one of 2025 with a possibly 2 bedroom and 1 bathroom single family home; as this is within my current budget.

@Ken M. we live in one, it has an attached unit, but with a door that passes through from both units.

New paint, lvp floors throughout, new bathroom.

After adding an extra bedroom and bathroom and rehabbing the house, I was well over budget.

I would notify her in person and in writing (big note on her door) including quoting the clause in the lease where she is responsible, and tell her you will be inspecting to insure the heat remains on, high enough to protect your unit, or she will be breaking the terms of her lease and also liable for any damage done in the downstairs unit as well.

It is usually much easier to seal a existing door way then it is to move walls in my experience. 

Home could've settled and nothing further to do or you could be seeing a bigger issue at hand that the seller needs to fix.
