Flipping a quarter to see who wins is not a good business model.My vote if you have no documentation is rip out the carpet, use some oil-based Kilz on the floor, and go over it with resilient flooring like luxury vinyl plank that is much easier to clean and repair when pets piddle. 

as you probably know houston has large oil and gas industry- specifically in my area there are many petrochem plants and such (ei: pipe yards, fabrication shops, drilling compnaies)

That varies Jon, but last year (2011), I put away about $68k of my income which was invested in notes, oil/gas investments, and 401k.

Securities are defined by the Securities Act of 1933http://www.sec.gov/about/laws/sa33.pdfThe definition is:The term ‘‘security’’ means any note, stock, treasury stock, security future, security-based swap, bond, debenture, evidence of indebtedness, certificate of interest or participation in any profit-sharing agreement, collateral-trust certificate, preorganization certificate or subscription, transferable share, investment contract, voting-trust certificate, certificate of deposit for a security, fractional undivided interest in oil, gas, or other mineral rights, any put, call, straddle, option, or privilege on any security, certificate of deposit, or group or index of securities (including any interest therein or based on the value thereof), or any put, call, straddle, option, or privilege entered into on a national securities exchange relating to foreign currency, or, in general, any interest or instrument commonly known as a ‘‘security’’, or any certificate of interest or participation in, temporary or interim certificate for, receipt for, guarantee of, or warrant or right to subscribe to or purchase, any of the foregoingSo, are loans securities?

I go through a lot more heavy coats of primer than I do sparing coats of paint in renovations, and while the bulk of it is Kilz2, a lot of it is oil-based Kilz Original and my problem-solving stink and adhesion primer is Kilz Complete.

So if i have to worry about a tenent that will break into my part of the house how can i get into rental biz and trust any tenants of any house i rent out.R2 how do you sleep at night knowing that in your huge empire of apartment buildings theres probably someone cooking oil from the weed they grew...down the hall is the ex con smoking crack and possibly burning your whole future.If i cant trust the tenent i bring into a basement suite i think i better think twice about getting involved in rental part of REI.Maybe rehabs are the better way less human factor

Sounds kind of snake-oil-ish to me.

They have thick wood floors and I just paint them with an oil based floor paint (thank you to Mike OH for the suggestion).

. $3600 (six months) Is if fuel oil, gas?
