I list them on Zillow for about $100 under market rent.

I usually end up with a list of buyers with down payments but I don't have any more inventory for lack of inventory (capital).

Zillow is listing more and more furnished units now as well. 

I am contacting homeowners on the pre foreclosure list, getting contracts.

Or, in most metro areas, you can obtain the list of permits that have been issued, and see who is receiving permits. 

There are cheaper one’s in D/F areas but I would be careful as those can create a laundry list of additional issues.

Charge $100 for the template and check off list.  

I know when I was an active Broker my SOP  was get listing open escrow with buyer to be determined and order the preliminary title report prior to spending money on marketing someones property..

There are several things to fear money loss on a bad investment, government involvement in RE, bad tenants that cost time and money, hidden maintenance issues and/or land issues and the list can go on.Today, I don't fear money loss or tenants,  the big unknown is how much the government wants to get involved in either taxes or landlord/tenant issues.

My interests includes but is not limited to co-listing Airbnb, short term, medium term or long term rental properties just to include a few.
