For small multi near UNLV, scattered 4plexes and small apartment complexes.

An 8-50 unit multifamily can be managed (or hire someone to manage) so much easier than 8-50 single family homes scattered throughout a city (or worse yet, throughout multiple cities).I also feel that both rents and prices of single family homes are getting more and more out of reach for the average person. 

Scattered site or apartment complexes?  

The cops come they scatter like roaches. 

I'd rather have rent on time at scattered dates than to have all rents due on the first and straggling in.

For a property with a little more complexity and scattered comps, I would use an appraiser every time.

There are scattered posts that outline daily activity plans for wholesalers & Realtors.It's been a long time since I had to have a "just starting out plan" and I am putting together some daily plans for those I am mentoring on identifying short sales and contacting Realtors.Any help, links, input from the BP community would be appreciated.

Just for giggles I did some quick math to determine 2012 expense ratios (Expenses/Gross Income) for a couple of my properties for which I have the data handy.4-Unit: 52%SFH: 35%2-Unit: 78%2-Unit: 34%2-Unit: 28%Sort of a scatter-shot...and it will be different in 2013 as new maintenance and repairs are done on some units, and other units require less upkeep as compared to this year.My experience (and I'm by no means the most experienced REI) is that the 50% rule is pretty close for my portfolio.

They have made a mess on the back porch by attempting to grow plants out there and they are all dead and scattered everywhere. 

I hope this helps.http://realtormag.realtor.org/daily-news/2017/08/1...http://economistsoutlook.blogs.realtor.org/2015/11...https://www.nar.realtor/field-guides/field-guide-t...None of the above could be taken as a statistically proven research and certainly does not support your thesis on 20% loss of FSBO- just numbers skimpily scattered through the pages.
