The majority of the odor was in the attic since the smoke rises. 

Holy smokes!

Any successful guru whose brand is his ability to come up with novel ways of doing things and is confident enough that his method is worth your time would probably rather make a ton more money by throwing out all the bells and whistles and smoke screens and lay out a simple marketing plan that offers a brief overview of the system, including the niche is serves and the type of properties you'll be finding in order to use the system.  

@Erin Spradlin I have no regrets having invested in my STR in the Smoky Mountains some 4 years ago and I’m actually now dealing with our 2nd natural disaster in the area with my first being the horrible wildfires a few years ago in the area that squashed almost all of a holiday season with significant expenditure on smoke damage.

Broken down vehicles, shady visitors, animals appearing, notices from city code enforcement, smoking. partying, domestic disturbances, on and on.Without appreciation, I would have netted nothing really for my 10 yrs of pain and suffering. 

Weed out 99% of them by immediately requesting a conference call on Skype where you see them on video.Scammers tend to hide behind a keyboard with smoke and mirrors.Legitimate mortgage brokers or lenders have no problem getting paid their fee when it closes.If a lender tells you everything is fine etc. when submitting your deal then run.

And enforce no smoking.

HiWe recently asked for fire retrofit inspection of our building as it is needed for refinance, some of the units didn't pass audibility test, so we added wireless interconnected (battery-operated) alarms into the units, but fire inspectors require hardwired interconnected smoke alarms or horns to be added to each unit, which was estimated at over $5000 on electrician work.We asked them to check with fire marshall, who said wireless interconnected (battery-operated) alarms are alternative solutions, but fire inspector still disapproves what we did because they don't feel comfortable about battery-operated alarms. 

@Aj Parikh I got smoked on a few Roofstock "deals".

frankly, I don't care if the lead comes via smoke signals.
