Looking at purchasing my 1st rental property and interested in advice from anyone with experience rehabbing older homes. It's a single family 3/4 BR, 2 BA in a hot area of NY's Hudson Valley, built in 1900. Looks good on the outside but inside it's a MAJOR fixer-upper; slanted floors, former tenants evicted and likely trashed the place before they left (it's disgusting). Kitchen/Dining room looks great though and house is located on an amazing, quiet, family friendly block near center of town. Bedrooms are small and no in-room closets (has large-ish hall closets and attic storage however), one of the bedrooms is a walk-through. Looks like damage is mostly cosmetic, house probably has good bones but won't know for sure until after inspection.

Asking price is about 2/3 of what houses like this in good condition go for in this area. I've run it through the BP rental calculator with conservative, medium and liberal scenarios and it looks like the property would cashflow between $450-$1,000 / mo. This house could also be a flip but I have not looked at that scenario in detail.

What are some things about older homes that I should keep in mind when deciding to make an offer? Are there questions I should be asking that I may not be thinking of? My main concern is the rehab, I know I need a good inspection before but don't want to get caught with any major surprises. Also, I'm concerned about the lack of closets in the bedrooms and the walkthrough (will it be hard to rent). I live about 1.5 hours drive south of the property, my schedule is flexible but I won't be able to run up there at the drop of a hat. We do have good friends nearby who are landlords/realtors who have offered to help. 

Any advice would be much appreciated.

Thanks!
