Rehabbing a large 1910 2-family home

[Devin Berrian]

Hi all, 

I am soon to close on my first deal - a 2800 sf legal two-family home in the City of Poughkeepsie, NY. The basics:

Build in 1910

3 BR 1 bath in each unit

hardwood floors are OK, need to be refinished but definitely usable

asbestos siding

31 exterior windows

front and back door access into stairwell/foyer

needs full electrical upgrade (still has fuse box)

needs full plumbing installed

needs full hvac system

doing all carpentry and renovations myself aside from electrical (may end up hiring out plumbing too if the inspector will not let my Professional Engineer father-in-law certify my work)

I'm reading all that I can on BP to learn about what level of quality I should use in my purchases and renovations, but is there anything you wish someone told you when YOU began fixing up an old home you were going to rent out?

Thanks in advance!
