Main issues are electrical...service panel, cloth wiring, meter box size and plumbing...galvanized supply lines, caste iron drains might be towards end of life span, shut off and bath valves.

Within the CPI, the cost of groceries and electricity rose slightly in October, but those increases were offset by price declines for gasoline, car insurance, clothing, home furnishings and medical care.

They can't get into the basement to sniff for dampness or mold - or look for standing water. 

My Beginning:I am finally getting into investing and have just started this past August on investing my money in stocks, etfs, and cryptocurrencies(also my stores as well my girlfriend and I have a clothing brand that we just started).

I had a broken dryer in a unit that caused some burning to clothes. 

Don't try to split it out, as that won't work.3) Use a programable smart home thermostat- program it to alert you on issues.4) Provide a Washer and Dryer for use, and set up ground rules- move your clothes through. 

Maybe small lockers that the tenants could use for their laundry supplies-soaps, dryer sheets, etc.I would not put dirty bikes, etc in an area that is primarily for producing clean clothes.

Beyond buying food, clothing, and basic shelter, and maybe paying to correct health issues, all other spending is "discretionary", so it really doesn't make any difference if your hobby is playing golf or paying down your mortgage. 

What clothes does a house wear?

I had a lady in my office once made several thousand dollars over the course of a year selling used clothes she would buy in Goodwill and sell over Ebay and Etsy.
