The banks price them too high to make it worth while. 

If you hold the home longer than this and don't plan on another refinance than it may be worth while.

I don't really care what I am doing to make the money, just as long as the financial return is worthwhile then I am interested.

Could be worthwhile to buy the first one or two in cash and have no mortgage headache to start and tons of cash flow just so you can get a feel for real estate and whether or not your strategy works and whether or not you even enjoy it. 

Basically is i worthwhile to invest in trailer buying.

So go discuss with the permitting department to get a general idea of what is needed first, and then from there you can assess if it is worthwhile.

As an aside, the city that I live in has grown very quickly over the past 5 years, and I'd love to begin with a first unit to rent to simply get started along the journey.I'm currently seeking any worthwhile RE associations to join and network with, and will take on board any advice and recommendations the Bigger Pockets community is willing to share.

You have to remember that the LTV on the re-fi is going to be at 70%LTV and conservative...BRRRR really isn't that great unless you have a screaming deal...most folks that BRRRR with a lender involved get screwed when they have huge renos or unexpected costs with the combination of being incorrect on the ARV...it's really a pretty advanced technique...and there are very few places in the country where you can find deals to make BRRRR worthwhile....sometimes economic condition may create a good BRRRR climate, but those days are passed...

Makes me wonder too that are the people who end up buying these properties (which don’t seem to be good deals, assuming they are bought at the asking listed price) making bad deals or are there cases whereby even though something might not necessarily pass the 1% rule, it may still end up being a worthwhile deal to look into? 

Looking forward to having a part-time tenant manager to assist and part-time maintenance now that I'll have the number of units to make it worthwhile.2nd, the OP sounds like a smart, successful guy... but I suggest he drop the thing about the certificate.
