I'm a landlady and I would never bring an animal into a tenant's home without permission.

Ask seller/property manager/realtor for:Copy of rent roll for 2 years (how rentable is it..how much vacancy etc)Copy of current leaseGo talk to the tenants (ask permission) verify the lease and rent with themCopy of sellers Schedule E tax returnsBank statements verifying the rental incomeAll utility bills - at least 1 yearWater billsInsurance premium bill for the propertyProof of ownership on all appliances etcGo online and check for any serious building violations And there might be more but that is a good start.

Better to beg forgiveness than ask permission sometimes @Austin Davis!

He puts the claim in on his insurance and his company gets the money from the other person's insurance company.As soon as he gave you permission to enter, you don't need him to be there-you can enter AND if it is an emergency, you do NOT need his permission to enter (eg a burst pipe).If he has been horrible since day 1 and you've had issues with non-payment, why have you not hired an eviction attorney to evict him?

Anything longer than that needs my permission.

there are some municipalities that will issue permits for the signs, so maybe you could get permission to use them.

We find that suspicious - are there any services that allow us to do a background check without asking the landlord's permission?

need to check with the seller.. they may or may not allow this .. get permission if granted go for it for sure.. cheap insurance.

Sometimes asking for forgiveness is better than asking permission.  

I am interested in a property that has an interesting deed recording. US Bank took over 1st lien position per registered deed. The borrower took one mortgage from Fifth Third is 2008 and took another lien from US Bank...
