I've even talked to other family members about combining our lots and creating a small community of homes.

@Vic Hartounian absolutely - leverage should be used inasmuch as you are comfortable, and there's no reason not to combine a cash and leveraged approach. 100% agree if you do OOS turnkey the team is what makes or breaks your investment (although to be fair this is also true of OOS BRRRR - but you have to build the team yourself).

The fact they are taking the unit sight unseen combined with the bribe often means once they arrive they will begin looking for a place they really want to live in and they will be gone at the end of the 3 months. 

The point of all this is to find strategies to improve lead generation specifically by combining and integrating and complimentimg diffferent stand alone lead gen strategies.

Easier to find financing if you have some "Skin in the game" Equity can come in many forms, cash, devalued purchase, sweat equity in rehab. portfolio loans with combined equity of other properties.

I am thinking of using a conventional loan (to the amount I can qualify for) in combination with a hard money loan, then BRRRRing the property to repay the hard money loan (after a refi) and keeping my conventional bank loan.

The west side of the metro seems to have the best combination of growth, value, and long-range desirability.  

In the discount brokerage space that is about the best combination of price and control of outcome you can ask for.  

After scoring the brother/sister separately, I would combine their score for a total and then determine if they are denied, approved, or approved with contingencies.That's probably too much for you so I would just consider the general risk of each individual.

You might also consider talking with different lenders and seeing which lenders will do a 401(k) loan that combines and FHA loan with the cost to rehab built into the loan. let me know if you have any questions, I am in Utah, and I’m trying to do the same thing but the only thing that’s stopping me is my credit score and financing the down payment.
