Accepting any payment will make eviction more challenging but some states/localities prohibit you from refusing partial payments, so you have to know your local laws.

Is this true?

This is especially true in appreciation markets.  

True the new owner will have to start his own account, but he should have a built-in revenue stream from repeat guess that will search for that property by address.

Some investors have found that working with the right team even in challenging markets can be a pleasant and profitable venture.  

The challenge, as you’ve discovered, is that traditional HELOC lenders typically want the property titled in a personal name rather than an LLC.

Or a PM bizz  etc etc all of these are RE based but you dont need to own any RE per se . when you have investors that are not in the bizz IE not brokers lenders GC's etc etc they to me are true investors and depending on their background and funding ability scaling can be a pipe dream or one can methodically do it in what ever rental props they want to buy..

For practitioners in the real estate industry, the biggest challenge is not just the difficult work, high risks, or immense pressure, but the necessity to learn to let go of complete control over outcomes.

However I  do want to know why you think the statement above is true..

If you get dealt that character card, your primary challenge is that you need to replace a lot of income to get out of the rat race.
