We're about 90 percent through this one, just kitchen and floors left.

The property needs a complete rehab - flooring, kitchen, bathroom and painting, etc. the property is around Pomona area. 

Do you mean down to the studs with new electrical and plumbing or are you just talking about cosmetic renovation with new cabinets, flooring, etc. 

I can have someone periodically clean them up.. would that be more cost-effective than spending it on gutters?

With little to no experience in pricing out reno I run a low end estimate of 10k to refinish hard woods, lay floor in bath and kitchen, hang drywall in all 3bed and 1 bath, and paint everything.

KNOW what you get for different price points as far as quality of construction, cabinets, faucets, flooring, appliances, etc.

After they moved out, I was doing the tenant turn over (cleaning, painting, etc) and one day while I'm there it starts to rain. 

"We strive to provide safe, clean, affordable, comfortable, and quiet housing for responsible renters."

Are they keeping the place clean - no holes in the walls, etc?

I estimate some electrical work, kitchen rehab, painting, & flooring.
