@James DuncanI love PI but you’ll want a person who is a citizen (they limit foreign ownership) and is trust worthy to oversee the property and collect rent.

This may not help at the moment but you can find trust worthy lenders that same way you would find anyone else that is trust worthy.

But I'm a little lost where I can find a reasonable and trust worthy lender to work with and build a business relationship with because I'm looking to buy at least 10 rental properties by the end of the year.

The real estate industry operates in the "Trust Economy" and trustworthiness is a possession my team and I hold dear. 

Very trustworthy as well. 

They have been managing my properties for the last 3 years and have done a good job and are trustworthy and have a good team in place to manage properties throughout South Texas.Send me a PM and I'll give you the contact information.

I'll probably need all the contacts i can get in the way of trustworthy contractors, other members of my "team", etc...I'm currently an RN at a local hospital, but my goal is to one day be able to support myself through long term rentals.  

Who it is from depends on the person receiving it some people want to deal with what appear to be larger companies because they seem more trustworthy others prefer independent buyers to try to get a deal.  

For turnkey, it can be more important to pick a trustworthy and reliable company then it can be the particular market, which of course has to be economically healthy and cash flow possible as well. 

Build a trustworthy team.
