I don't know the numbers really well in those areas myself but I'd imagine you can hit that sort of number in those areas. 

@Alex Shin imagine if you self-managed.

I would imagine if you are going to buy you should be able to ask for the rent roll and copy of the lease. 

I imagine realtors have plenty of work so they aren't interested in doing extra legwork for a potential deal. 

I imagine their contract allowed them plenty of time (although the seller did not know it was being wholesaled).

My first plan was to collect e-mails of nearest businesses like gyms, schools, salons, banks, etc. and sent them bulk offers to install the machine.

Quick simple cards that have your name, number, email and maybe a picture of you so that people remember you. 

Tell the attendees you will keep them notified by email list or Meetup notices, which ever you choose, and then either collect those emails, or ask them to join your group on meetup (emails are more reliable).But make no mistake, running a group is work, even if you keep it simple. 

We give you a dedicated line for your tenants to callWe diagnose if the issue is an emergency or notWe troubleshoot the issue with our own team to try and get a fix done over the phoneWe will get a contractor out to the home asap if we can't fix the emergency on the phoneIf it is a standard request, we'll email you and see if you want us to send someone out to fix itIf you think a service like ours would save you time and hassle please reach out.

Dear BP community,I was wondering, where can I learn more about real estate professional business ethics and conduct (writing the right emails, talking to people of the phone, negotiating, accepted norms and standards, and etc.)Do we have such resource on this website?
