Does anyone have any advice on effectively setting up temporary battery-operated cameras on a long-term rental property to deter break-ins and squatters while rent-ready repairs are being made before a tenant moves in?

So, WHY screw with a successful system that your able to operate without undue stress? 

If all prospects and leads come from yourself, then you are operating your own business.

And many hotels don't have 24 hour desks or 24 hour service.I don't get why all these newer regulations expect STRs to operate to standards that aren't even required of hotels with full-time staffs. 

Deduct mortgage interest, property taxes, travel, and operational expenses.

Is it Leasing, Property Management, Vendor Management, Operations, Finance, Accounting... 

I've gotten good results from Ninja Skip Tracing and Skip Matrix for my cold calling operation.

Hypothetically, if I found a property with strong rental demand, the income could cover loan payments, operating expenses, and generate a modest positive cash flow.While this example involves upfront risks, the idea would be to leverage my father’s expertise as a contractor to minimize renovation costs, boost the property’s value, and create a long-term asset that appreciates over time.

Hiring a property manager is highly recommended to handle day-to-day operations and leasing.
