The good news is there should be products still out there. 

The decent producing Realtors, the ones that sell a fair amount of homes, already know what's up and aren't doing a lot of hands on hips drama routines with pointless threats and all that (top producers never do drama routines anyways, it's a characteristic of being a top producer, and in case someone takes this as gendered commentary because I referenced hips, it is decidedly not gender specific, drama propensity is equal opportunity in this case), but the lower producing realtors are all working on their Ph.D's in Drama Llama Sciences. 

I’m an investor with two cash producing homes and looking to shift my focus into BRRRR properties.

If I understand what you're describing, it sounds like your lender is being particularly aggressive and probably does not want you to refinance out of his/her loan product, though that is your choice.

If it is now finished, then I would load it up with 50-100 pictures of the finished product, including interior photos.Why has price gone up $500,000?   

The best rates come mainly from the company they work for and their associated programs/products. 

Local lenders with credit unions may have quirky loan products that you wouldn't find at a big box lender but this is not always the case.

A lot is going to depend on how you're situated and how that matches up with the loan products they offer. 

Who has products in the space and what options are recommended?

That doesn't mean it is a bad idea, but it does mean you need to redeploy that cash into other investments that produce more income.
