I would never go with a national lender suggested by a turnkey company; reason being they most likely have higher rates because they are being fed leads by turnkey companies and need to pay for those affiliate deals.Rates change daily so if you're shopping for quotes ask for the same rate with the same down payment on the same day from multiple people to ensure apples to apples comparison. 

If I was backed into a corner and I had to join one program/mentorship, I'd focus on joining a mastermind based on who's affiliated with the group and the value they provide.

This is not an affiliate promotion, just a recommendation.

I used my VA loan and military affiliation benefit to purchase four homes with three of them being a VA loan.

While I do not have a solution about the sliding glass door - We use Schlage encode with Lynx automation and it works great. 

Please note I am not affiliated in any way with any of the groups other than that I have attended some of their meetings/presentations.

Check out this video (I have no affiliation with the law firm, they just have a tone of great info for PMs and Landlords). 

Which is why I think awning.con is what he is looking for (I have no personal affiliation, I just use the site)

You should check out SJREIA they have plenty of attorneys that are business affiliates.

I can essentially serve as a property manager: tending to the house (cleaning, maintenance, etc), working and coordinating with any affiliated contractors, and I can even perform rent-roll, T-12, or DCF financial analysis for you on the property, or look for other properties as well.
