Landlords can enter a tenant's property for a variety of reasons, including: Making repairs or replacements Responding to a tenant's request Removing unauthorized window coverings Preventing waste of utilities Changing filters, testing, or replacing smoke detector batteries Inspections Helping with an emergency inside the unit Posting a notice of eviction"Research your state laws because some of your comments indicate a lack of understanding of the landlord/tenant laws where you are operating (like threatening the tenants to keep the security deposit if they don't respond to you, I doubt that is actually a valid reason to keep their deposit, or evicting for late payments, or charging the tenants for your warranty repairs because you missed your 11 month inspection window which was your responsibility, and it looks like your lease says you can charge up to 18% interest for unpaid fees, is that actually legal?).

I understand in NJ, landlord is not collect to charge pet security deposit.

What’s the best way to secure a deal, and not encounter with another wholesaler going after the same property.
