I am very particular the process and SOP/SOGs of filling vacancies and prescreening etc...and this platform doesn't really allow for my hybrid style to use the application/website for my needs, but my own personal data and forms etc simultaneously. 

I then also spoke with an LADBS zoning person, who said that you can submit your permit application for the second SFR, and as long as it's attached to the existing SFR, you could simultaneously submit for 2 ADUs!

The first that can generally be cut is the Simultaneous Issued Lender Policy costs from $350 to $650, down to under 100.00 and down the list of fees from there.

Can you push out price updates, etc. to all platforms simultaneously from a single calendar?

While loan assumptions can potentially be leveraged for lower debt service, assumptions simultaneously impact risk factors for an investment.

Right now I plan on doing a few flips simultaneously but I'm torn on what to do about the rentals and how to maximize my loan over the 7 year term.Do I pay off my current properties and find good deal properties and pay cash up front?

The strategy on when to "lock your rate," is also very important and it is advise that you balance the timing with your closing time frame for your purchase as well because you "do," need enough time to close while simultaneously planning for enough time to do your inspections, appraisal, and financing items before you rush to lock.Currently as of today, the market is priced a bit better I do encourage you to check in next week after MLK day (federal holiday markets arent going to be open) to see how your pricing fares.I would estimate you should be in the 6.875-7.125% if you pay around .50-1.00 but there may be additional variables. 

I am interested in knowing how many brrrr deals would you so simultaneously?

I would do both simultaneously and work towards finding the right property and the right lending partner.

The extra cash flow from the rental helped pay down the loans and I would personally take that approach again.Since you are engaged and are saving for the day, it makes sense to simultaneously pay down loans with the highest interest rates first or you can use the snowball debt reduction method.
