Hi @Jordan MoorheadI welcome all lectures at this stage of my learning curb... common decency goes a long way especially in sensitive situations where you are asking someone to move out of a place (they hopefully like) that they've called home over a decade and have been paying next to nothing.

Being a successful real estate investor or wholesaler starts with not being shy about asking all the questions you need to get the answers you have to have.If you're dealing with a motivated seller and you're too squeamish to ask all the questions required to build the required rapport and ask all these questions, you'll definitely regret it down the road and it may be too late then.Avoiding the Almost-Insane Customer I really apologize to you if you're one of my sensitive readers, but you'll find out if you really want to go out there that some people are really emotionally maladjusted enough to be considered almost-crazy.Every landlord or homeowner that I've ever regretted dealing with came with warning signs at the very beginning of the communication process; warning signs I should have heeded.

The 5+ multifamily space is a lot more sensitive to rates. 

Learn what documents they need from you during underwriting to understand their process better and know what sensitive information you'll have to disclose. 

It takes planning and restraining oneself against impulse, and this feels like severe pain to most and they can't tolerate it.
