I'm not part of the sect of BP that seems to believe tenants are subhumans who exist to poop out money for the landlord or else crawl off to rot and die elsewhere, but you will have to set rules and stick to them steadfastly.

I wanted to take advantage of selling my property at a ~3% cap rate before thousands of new units hit the market, driving down rents, and the amount of money in the market place drying up.I am now searching to invest in several properties that add up to ~100 units in the Sacramento/Central Valley area of CA.

You need dry powder for a deal if it comes up.I've been punching my debt in the face for a few years, but I am content and the mortgages deserved it.

However, as you'll see in this rather dry IRS publication https://www.irs.gov/publications/p590b/ch02.html, you can avoid this 10% tax if you use the amount over your contribution for qualified exception, including the purchase of a first home.

If you are over 50-60% start systematically reducing the introduction of moisture and increase ventialtion.Make sure the basement is dry, if not check your gutters, downspout extensions and get a dehumidifier.
