But it is important that you communicate it well and have it written into the lease/rental agreement.

When the communication and payments stopped I asked for the notes back but only received two out of the four.

She communicates with all parties when I am unable to be reached.Biggest piece of advice.

I've written dozens of checks, so it's not that I can't - but when he wants a percentage up front and needs it to buy materials, cutting a check and being at home for him to pick it up so he can start in a timely manner is not the most efficient.

Just like investing in larger commercial deals, they have economies of scale so it’s likely that it’s also more efficient to wholesale larger deals over smaller ones

If you have a problem with the property you have to get a hold of me like a normal person and communicate.

Leeches and other bloodsuckers preying on those who are newer to real estate.Brokers and agents are relics trying to hang on to unnecessary commissions and wasted money when technology can do almost all of it without all the horrendous commissions and charges.It is called an efficient market.
