After checking the Houston market, I've found that rents are typically only 30% to 50% higher than long-term rental rates, which makes rental arbitrage seem less viable.I'm wondering if these hosts might be exaggerating their profits to sell their expensive courses.

I liked him and what he was offering (and being in the coaching space myself, I’m not at all bothered that he was selling something) but I’d never heard of him before, so I wanted to do a bit more digging before signing up.I am curious if anyone in the BP community  has had experience specifically with him, his courses or coaching program and would mind sharing their thoughts.

They have a lot of training available for things like prompts, activities, tracking for renewals, etc.

Of course, putting more down like 30 % would make it look like the property cash flows well, but is it worth it to put that much down, or is 20 or 25% down better depending on which gives you a better interest rate?
