However, simultaneously we are selling our primary residence that we have been in for 4.5 years. 

I , however, don't think you may get the loan for the property because you are technically taking out 2 loans almost simultaneously.

They depend on cash flow to pay bills and grow wealth simultaneously , all be it slowly.Those starting with the goal to grow wealth can invest in over priced areas where descent rent to property price are unattainable.

You can close them simultaneously, or in quick succession, so the Seller shouldn't care if you do it this way, or by 1 loan.By having them untied, it will give you more flexibilty down the road too, in case you want to sell one and not the other, or refinance one. 

I'm also curious as to why you are moving on 5 properties simultaneously. 

I thought i could do both simultaneously and im likely to lose a 4-plex at this point cuz i didnt realize lending is much more difficult to get when new and unproven.

I would network in all of those circles simultaneously and if the right deal comes around, the chips will fall into place.

As long as any 1 parcel is 1-4 unit, you could close them simultaneously, or in short succession.This would allow you to obtain the portfolio at a discount (if one is offered), AND receive the conventional financing. 

great questions.. by building a team we simply go back to how turnkey was done pre 08in CA this will be quite difficult as you will have to build all the components of the teambut in time lines1. you need refi lender all set up2. you need market identified and rehabber or turnkey out fit your going to work with.3. you need HML who knows and trusts the refi lender AND the turn key out fit. once you have those in place turnkey outfit presents home to you and HML.. its a joint decision to move forward.. ( remember your refi lender has you already pre qualified so the property also goes to your refi lender to start the process simultaneously to the HML going into force.put up your down payment money HML closes and HML does rehab draws to your trusted turnkey vendor or flipper.. once all done your refi lender who has your file already to close subject to a 442 orders 442 and you close... ( refi)  HML gets paid off you get the house.

They MAY be able to do them simultaneously, or possible staggered a day or two part.The lender should be able to use 75% of the rental income to help you qualify for the loan.
