I considered doing a quick claim deed, but that would trigger the due-on-sale clause and I don't want that.My question is how do I structure an agreement with investors to allow them access to both equity and cash flow?

Second, your PM should be providing you with an analysis of market rent, they have access to what their other clients in the area are currently charging.Once you have a solid market rent, your PM should let you decide how much to raise rent, unless you want to hand that over to them. 

Second, what do should I do before approaching the homeowner to ensure I can legally acquire the property. 

I would not allow them access to his belongings until they paid. 

Similar if it has difficult to assess access/easments it may not get redeemed.Of the list of properties we had interest in when we started, we are down to 4 potential properties (5 if I count the one with the access/easement potential issue) that are not currently redeemed that after visiting we still have interest. 

Our current status is we have recently acquired three duplexes.  

So, lets say we go to the courthouse, acquire a list of prospects, and send a mass direct mail campaign. 

I don’t think that’s accessible to you or me.

It's not what I would call a BRRRR, since it doesn't need a ton of rehabbing, mostly finishes inside.Here's the question: How should I use this HELOC in the best way to acquire more rental properties?

@Victor Barboza that’s hard to say with out seeing the pitch, stories of house, access to the roof.
