Remember also if you are getting the properties at good prices you are getting a big chunk or all your investment back when you refinance. 

Hi @Michael KaySome options for a property of that size could be:Seller financing with little money downObtain bank financing and ask the seller to carry part (or all) of the second (down payment)If it is a really good deal and you can actualize the upside potential really quickly you could go with a hard money loanIn a similar vein to the hard money loan, you could partner with another individual for the downpayment.Those are just a couple of ideas to get you started! 

When an owner gives you a master lease with an opton to purchase, the owner is relinquishing some or all control of the property (regardless of how legal or equitable title is held).  

I would also talk to an long time experienced building inspector in that area that maybe aware of any restrictions or building issues that he may know about in doing what you want to do there.Make sure you understand any or all investment conditions put into writing as well as any obligations that are financial or monetarily involved. 

Your best bet would be targeting investors who own the entire property that is most likely renting out both or all units.

Sam - Are you interested in selling  one or all of these or looking for a partner to do more deals with?

What you need to verify (but I bet it is the case) is that just because a property has multi-use zoning doesn't mean that the building has to have multi-use spaces - it can be ALL residential or ALL offices and stores.

You could certainly make an offer, subject to inspection contingency, appraisal contingency, loan contingency, or all 3 which would give you the time to do your diligence.

Or all of the open houses and potential people on craigslist, redfin, loopnet.com, etc.?

Now it may be that multiple or all of these members of your team are under one roof or all under different roofs.
