Does the new tenant have pets?  

Second example is we discussed no pets inside and that is on the posting for the house listing....however that is not in the lease either.

Yes I agree, the owner's are very strict on who they let rent from them, I do know they allow no smoking and no pets, ect, but as I was explaining to my attorney, if there's a problem later with the tenant, how can I enforce the lease if I don't have a written copy?

I tend to drop by during first week or two of tenancy to "make sure everything is ok" - also allows a quick survey of housekeeping, undisclosed pets, etc.If it's an outside inspection (City, Section 8, etc.), I let them know as soon as I know the date (usually a few weeks ahead of time).If you want to inspect the unit regularly, you could write it into the lease and schedule as far in advance as possible, with a 48 hr (or so) reminder...If you are inspecting because you suspect a problem, in many cases prior notice would not be required (for example, emergency repairs).

Some condos have rules prohibiting or limiting rentals, or pets or another aspect not conducive to your investing goals.3. 

It is actually nice collecting a late fees, extra revenue.One thing I did start in my contracts was going away with the pet deposit.

(If they say anything negative about their current place or landlord this is also a sign).What type of pets do you have?

( new pets are not peeing in the spots where the last animals did)I meet the seller at the property Saturday morning to go over everything.If buying at the right price anything can be a good deal!

I take care of animals for a living (own a pet sitting company).

I did drive by occasionally to make sure there were no dead autos or campers in the front yard.My agreement states no pets.
