I just send you a connection request. 

We routinely pay $100-$150/night, because the solitude and unique experiences are completely worth it.

With a bit of planning and good operations, one can easily manage 20 to 30 properties without an assistant, with less than a day or two a month.There's lots of automated ways to check on rent, make deposits (my tenants deposit directly into a bank account), receive maintenance requests, have maintenance done, etc., etc.One thing I could argue is to have your tenants ONLY email you, especially for maintenance requests, and that email goes directly to the vendor that you have set up to handle it.

Legal Mistakes Can Lead to Lawsuits or Tenant ClaimsTexas has landlord-tenant laws on security deposits, repairs, evictions, and fair housing compliance.If you mishandle security deposits, maintenance requests, or notices, your friend could get sued or be forced to compensate tenants.Evictions require proper legal procedures.

After the inspection, we sent a request with a mortgage contingency date extension (because it was also difficult to schedule this with the agent), a credit for termite treatment and an extension for the closing date which would allow one of the current tenants to move out at the end of this month (when their lease is up) before closing.

(Google to find one)Well, let's start with your post - it's so vague, we have no idea if you're referring to a 1-unit or multi-unit property.Also, you state, "I specifically requested to not mention anything regarding different ways of how to collect utility or rent" - yet your post is full of so much fluff that has nothing to do with your actual question! 

We've sent out a cohost request and most hosts are asking ~22%, which is higher than what ABB suggests - but seems to be in line with what traditional local prop management places charge.My question: Long term obviously it makes sense to learn to do this all myself and be self sufficient.   

I know you didn’t say this explicitly, but to me, your request says: “I want to borrow money from you with the ability to walk away from the debt, free and clear, for any reason, and leave you no way to get your money back.” 

They have twice given me notice that they were prepared to initiate eviction proceedings at the owners request, due to late or incomplete  payments.

Responding to tenant requests, leasing, coordinating maintenance, paying bills, and the accounting is only part of the job.
