Im holding a ton of doors in NC and Fl...and wanted to execute lease options..When it comes down to actually finding someone local in reality who is doing it as landlord and loves it and talks highly of it, with a duplicatable system, i have yet to find....i can only get resistance, discouragement, bad stories..Locals, ie, realtors, landlords, attorneys, prop mangers, on and on, all will speak negatively about it, and even against it, even though/if they have never done it..its not common practice here (jax) or NC..and misunderstood and seems to be judge to judge..in NC and Fl to decide how much headache and pain you'll be stuck with, when tenant goes bad..The 2nd worst case scenario you have to foreclose, not evict, because of tenant equitable interest, and 1st worst case you'll have to reimburse a tenent who has inflated repair-rehab made up invoices before a judge saying you have to reimburse them...these two scenarios are possible, real, and potentially devastating and i'm not sure how to avoid or minimize. 

Dang.

As @Michael Dang mentioned you could be a sophisticated investor in a 506 B offer, but you would have to be an accredited investor to invest in a 506 C offering. 

Are all my invoices uploaded to my owner portal?

I will need to calculate the interest due and then send an invoice monthly with the amount due.

It is really convenient for the tenants because I can just send them an invoice and they can instantly pay me, then I can send my funds to my bank in one business day for free. 

It also gives you one consolidated calendar, and allows you to print invoices for handymen, cleaners, or property management.

If you hire the person as a professional (like a handyman), you will be invoiced.

I have heard things are heating up in the OKC market recently, dang out of state investors!

In theory they should be the mailing address for anything relating to the property and they should present you with invoices for approval if you want to do it that way.
