You can cover the wire mesh with drywall patches (they tape on wall and across the wire, white/paintable, different sizes) as the wire mesh is what will prevent the rats from eating their way into the property (the covering material is cosmetic only).

At this point, I would recommend having a line of credit to cover these things so you don't have money sitting in the bank doing nothing when it could be put to work.I have 33 units, no debt except for mortgages, and excellent income.

The building tradesmen are busy too, but I just called ABC and got the name of a guy who buys alot of bitumen roofing so as to get a quote on a leaky patio cover, got a guy to bid cement board skirting on a stick house by calling Palm Harbor mfgr home sales center, got a card from a guy working across the street doing drywall repair and put it in my phone.

If one or more units are vacant, the remaining units often don’t provide enough cash flow to cover expenses, making it harder to meet operating costs.Maintenance costs: A fourplex comes with four times the appliances, plumbing, HVAC systems, and other components to maintain, leading to significantly higher repair and maintenance expenses than single-family homes.If you want to see the detailed calculation, read this BP blog - More Units Doesn’t Mean More Money—Why a Single-Family Home Can Beat a Fourplex.Resale value: Multi-family properties have a limited buyer pool—mainly investors—who base their offers on CAP rates.

It's amazing what you find covered up in these properties.

What surprised me is that USAA covered all of those houses.
