Although you have no legal obligation to tell them, most states require some kind of notice before entering the property to show it to prospective buyers.

So far as wanting more security, maybe they want to deter anyone from stealing there packages from their door.

As you will find many prospects you come across will reject your cash offer and will want full retail value.

Now I'm just wondering if I find that property manager to handle the day to day while I'm there and not have my prospective future tenants know I'm the owner. 

I know there are a lot of questions a prospective tenant may ask a property manager when viewing a property.

Ask to see the financials of your prospective tenant.

Rona,Did any of the prospective tenants pay an application or credit check fee?

I'd need to tap into my primary home equity to get the ball rolling unless I did a loan up front for the prospective property with like ~80 LTV.  

I buy stuff that needs full rehabs at deep discounts, and do full rehabs, New furnace, water heater, electrical panel if needed, flooring, kitchens, roof, windows, ect as needed and force the value up, so I tend to buy between $20-50K so $10-30K rehab and get an ARV between $80-120K with rents at unusually .8-1% of ARV or 2%+of my all in cost, this spring boards you forward, doing BRRR without needing more cash, because you can get all your money back out, I try to keep my equity high and debt low with the prospect of economic changes over the terms of a loan, lots can happen in 15+ years. let me know if i can help, I have 24 locations, 27 doors Im in West Bend and have stuff all over WI. 

How can I file claims to credit bureau and the popular rental sites such as Cozy and Zillow so my tenants' future job and tenancy prospect may be affected?
