There is a plethora of lenders one can do a deal with, but I'm looking for an asset based lender who is fast, reliable and has excellent customer service. 

Let's say they manage 7 properties for a local investor with a rental range of $900 to $1200/month per unit - the reality is that they may put minimal effort for your business, versus much more effort for someone who is a significant local customer at a notably higher price point.  

My friend is currently a plumber and has the ability to do anything from create custom cabinets to building a deck from scratch, and everything in between.

I have an LLC (Single member self managed) I just started for general contracting/ renovations repairs for customers. 

Everyone I know is aware that I buy houses , I tell my customers , friends , etc .  

Also always get your own inspector who is diligent and loyal to only you. 

If you do buy the worst property in the best neighborhood, you don't want it to remain the worst property in the neighborhood - there's a point at which you want to do a better job of attracting customers than your competitors, and that's going to be difficult to do if your place is a dump relative to the rest of the neighborhood. 

That being said if I find a good agent I will be loyal to them as it’s hard finding good agents.

As for "investor friendly", I learn this saying from a customer of mine many years ago, "Cheap is not quality and Quality is not cheap".I believe in building long term relationships where both parties can make money.
