Lots of good, practical information, especially keeping emotions in check when investing in RE.I love SFH, but I agree with him about MF. 

Its a mathmatics problem, not an emotional one. 

Experienced real estate agents and investors in an area know of the things that can impact the usability of a comp that less experienced people will often miss - (e.g. if there is a "historic" district within a 1 mile radius which would make using a comp from that area less useful even though it is within a mile) Having someone who does not have a financial interest in whether or not a deal gets funded review the property is a way to help pull emotion out of a deal.Also, we don't send evaluators out to review a deal (thus having the borrower incur an evaluation fee) without reviewing the deal with them before.

Stick to the checklist and don't let emotions reign. 

Gifts and affirmations are low on my love language list (Gary Chapman), plus I'm pretty emotionally flat so LLing is perfect for me. 

I understand the emotional strains of running a business.

Make offers until somebody says yes and don't buy on emotion.

It was a difficult decision as my family is emotionally attached to this home but based on the financial gains of investing the tax free appreciation it makes sense for us. 

I was the kid in high school getting offers from private colleges over how high my test scores were, and I ended up ruining so much with drugs, toxic emotions and bad decisions. 

Just be very clear on pets you will/will not allow, make sure you understand the support/medical/emotional pets laws in your state as well.Ultimately, if you're screening your tenants correctly, you'll be choosing tenants who are responsible pet owners anyways....Hope this helps!
