If the tenant has an expected right to privacy in their yards/ patios  aka fencing, or if it is a SFH then YES give them a 24 hr notice.

She was the Responsible Broker for the company until I obtained my Broker's license, at which point we removed her from the company and she became an ordinary agent for me.

We didn't see anything out of the ordinary though. 

My opinion is ultimately the PM company should be held liable to make sure this vendor gets paid.The PM agreement states: (21) hire contractors to repair, maintain, redecorate, or alter the Property provided that Broker does not expend more than $ for any single repair, maintenance item, redecoration, or alteration without Owner’s consent; Leasing & Management Agreement concerning: (TAR-2201) 6-1-10 Initialed for Identification by: Broker/Associate and Owner , Page 3 of 11 (22) hire contractors to make emergency repairs to the Property without regard to the expense limitation in Paragraph 4A(21) that Broker determines are necessary to protect the Property or the health or safety of an ordinary tenant;3) Should/Could the vendor file a mechanics lien at this point?

Also a “7 bedroom” home may be listed as 4 bedroom on MLS with a “den”, “patio room”, “office” etc. so you really have to go look at the property.

They are taxed as ordinary income. 

It's silly to try to use them as a measure against ordinary investors.Real estate is the safest, with most benefits, way for the ordinary investor to grow their portfolio.

As a trade off you getting pretty nice benefit of tax-deferred growth.Distributions from Traditional IRA are taxed at ordinary income tax rates, and if you pull the funds prior to age of 59.5 you would owe penalties on top of taxes.

Are they looking for ordinary income?
