If possible, during rehab, address some things that will help you insurance wise later:- full upgrade of the electical- full upgrade of the plumbing- removal of any sheetrock, trim, etc with lead paint- new roof- address any drainage/leaky basement issues- hardwire smoke and CO detectorsI know not all will be able to be done but most are cheaper during a big reno and will make you a better risk for the insurance companies. 

I struggle with cash flow and I do my own roofs and a fair amount of my own maintenance.Once you start paying properties off your cash flow picture will change dramatically. 

The HOA is great -- just $337 every three months for each house, and they take care of the exterior of the houses as well as mowing, edging, and pruning (except for a small area in front of the bay window on each house), and they replace the roof every 15-20 years.

I put another $7,000 into it, rented it out, a few months later put a $4,500 roof into it and I can sell it for about $45k.There are good deals if you plan on doing the work yourself...I'm not seeing many exceptional deals though. 

Also, roofing cement really shouldn't be used on a pitched roof, there's no need for it.

Do you know when the last time the roof and HVAC were replaced?

I️ bought a turnkey property, they had a new roof, new furnace, new hot water heater, refinished floors etc.

What I learned when I bought: (1) I had mice; (2) lease violated almost every law in Ohio; (3) rent was not "late" until the 15th of the month; (4) gutters were installed wrong and front porch roof was damaged; and (5) the bottom tenants decided they didn't like the house and were not going to pay rent. 

The economy of scale for 4 vs 6 unit is realized primarily in the exterior paint and roof costs per door, which admittedly may be significant, but probably not a deciding factor.Hope that helps!

When I buy multiple things on a reciept I don't know how to entet different amounts into what category.example: Buy paint, a tool, and all the supplies to put on a roof on the same reciept.I assume all the material for the roof goes together but in what category?
