So far, I've reached out to a company called Lloyd Security who appear to be able to help with wifi surveillance and access panel.   

Through a hard money lender, but I will take out a DSCR loan in March to refinance.

Strategies like living in a duplex or triplex, adding an ADU, or renting by the room can help maximize cash flow while leveraging FHA or VA loans for lower upfront costs.

and I was just one little mortgage guy with 450 loans out.. can you imagine the banks with hundreds of thousands of loans and servicing companies.. so having mass equity or paid for keeps this from ever being an issue. then when I sold these off.. most for cash but a lot I did a 30 to 60 month ZERO interest deal on.... and boy you should have heard the cash flow cool laid drinkers..

one of my clients that has a pretty big PM company.. had a unique way of doing this.He offered 50% of the first months rent or 500.00 minimum.. he would have 4 or 5 agents at the weekly meeting handout the list of vacants .. each of them would go place a sign in the yard and first come first served.. he found that potential tenants would call the first sign if no answer they called the next one until finally someone answered.. it worked pretty awesome for him. 

The mold remediation companies should have the skills to identify the source, suggest a solution, and give you a bid with a guarantee of their work.

Use your W-2 income to qualify for multiple loans now, stack a few properties before quitting your job, and consider BRRRR or DSCR loans later to scale.

I'd need the interest rate to be roughly 5% to breakeven on an interest-only loan, and was considering a balloon payment in 5-7 years.
