Obviously you will need to  be able to buy something if you choose to sell your primary, I would advise talking to your lender on how to get creative on that side of things.  

Here's the advise that I can tell you:Not all Section 8 tenants are created equal. 

Hello fellow RE investors,A quick question I need advise for.

Thanks Hey Don, To answer the "is there a different way to look at this" question I would strongly advise you real out to a real estate-focused accountant. 

Not just a lender who can put together a loan document (they all can do that), but someone who is interested in your goals and can advise you in different strategies, downpayment assistance programs, etc that can get you going.From there your financial strategy and the local market will begin to steer you in a direction of homes available and that fit your finances.

I've recently seen people giving advise to take out a HELOC as a means to pay your normal everyday expenditures including bills, and at the same time, taking your paycheck from job and applying it every month towards your mortgage payment.

I understand how to get to an ARV, account for repair costs, the hard/soft cost of financing, and so on.What advise would someone give in locking up deals?

Same intel that pointed me to saying rates will be at the lowest in any 18-24 months span during Q1 '23 back in Q4 22 when things were getting murdered, and clearly lots were advised that as we saw some aggressive Q1 '23 folks in REI.This is incredibly hard to pick and in my opinion the best solution is still to be quite conservative, but not stop investing.

Like @Russell Brazil advised above, make sure you write-in some sort of inspection contingency into the offer.
