First house hack - how do I get this property inspected?

[Adam L.]

I went out to view a 'short sale' duplex property for my first house hack and it has potential to be a good deal. I have the following hurdles and would appreciate any advice!

1) The property has two units: 5 and 6. Unit 5 was evicted in early March. I was able to tour unit 5 and I think it has nice renovation potential. Unit 6 we were not able to tour. According to the realtor the landlord did not want us to go inside because the tenant is in jail and the tenant's girlfriend is presently living in there. Unit 6 has not been paying rent. The realtor told me that the girlfriend is basically a squatter. The realtor was encouraging me to make an offer and perform an inspection on the exterior and only unit 5. She recommended I could then evict unit 6 after acquiring the property and perform an inspection on unit 6 after the eviction. This sounded extremely risky as my first deal and I don't think I would be able to get insurance or a mortgage without a full inspection? Not to mention the eviction ban, right? I thought about approaching Unit 6 and offering to pay them some money so an inspector can come inside. Does this seem like a potential solution, or do you recommend another approach?

If I was able to have the entire duplex inspected and my offer was accepted could I do the renovations on unit 5 and the exterior, then evict unit 6 after the eviction ban expires? Does this seem like a feasible approach?

2) The duplex is attached to a single family house (SFH) in the rear. I confirmed with the realtor that these two properties 'share' a roof. While touring the property I noticed that there is a tarp over the shared roof that is covering both the duplex and the SFH. I did some digging on who owns that property and it appear that they entered into a contract in June with a roofing company to fix their roof. The realtor asked the duplex owner and replied that "there are no issues with the duplex roof." Should I try to reach out to the owner of the SFH to see what the roofing issues are, and maybe coordinate with them if needed? I was also thinking of having the property inspected before making an offer to see if there are any overall issues besides potential roofing issues with the duplex, but I worry about the fact that it is a shared roof.
