I've rented a few places in the Phils over the years...never had any problems.

One month rent plus one month's rent deposit is pretty normal.

My last place we were in for 3 years, renewable annually. At that point the landlord may ask for a 10% increase in rent (which I believe they're entitled to do )

I agree, take dated PHOTOS of the place before you occupy it, and periodically, to cover yourself against any damage claims.

You'll also need deposits for services... electric and water.

As with any landlord, just COMMUNICATE with them about any changes you want to make...running a business from the property etc, and things will go a lot more smoothly.
