Would anyone know if there is a difference to these or if they could recommend any other sites?

I have extensive experience in calling different lists such as:Absentee OwnerVacant LandsFSBO'sPre-ForeclosureEvictionProbate leadsI have experience in making outbound cold calls to homeowners and generating qualified leads.

Yep, when I'm driving or biking and taking different routes to get to where I'm going, I keep an eye out or 'drive for dollars'. 

From the single-member LLC, i pay myself 100k last year to max out on the solo 401k contribution, while still having a W-2 as an engineer as my main job.my main job pays me 170k/year (Google)my single-member LLC rental pays me 100k/year (as S-corp structure)my question is regards to the payroll tax, i know I already max-ed out on the payroll tax on the employee side, any additional payroll side as employee will be refunded in my tax return, how about the employer side.

Hard money is for different types of projects/situations.

If yes, then maybe consider a PM software like Hemlane, which will give you access to leases from different states and rocket lawyer.

Advertising only consists of main websites: Zillow, Trulia, etc.

I'm sure this time won't any different. thanks in advance. 

However, IMO these animals are not protected any different than any pet if they do damages.  

Try calling from a different number, pretend to be someone looking for a property manager for a new property.
