I'm currently working with a lender that has a $50k minimum, and his rates and customer service have been great so far.

Quote from @Nicholas Dillon: I read somewhere that you can request to have your mortgage insurance dropped once your Loan to Value reaches 80%.

Find the rate the lenders want to lend.

I'm an investor and also a licensed mortgage broker.

@Skyler Shively, as mentioned, it is a tough niche to find a lender for. 

I walked to the house and met a man who says he was cleaning out due to the loss of their mother in some few weeks back.The guy told me she is  left with 12 years mortgage on the property to pay the bank.

But if they don't willingly make the payment your only option would be to sue, and they have the upper hand to let the lender know about the sale possibly triggering DOS.

I've come to realize paying down my mortgage is the best investment I could make.

Incensed deal flow by developing a large list of contacts of commercial mortgage brokers using LinkedIn.  

Paying it down faster doesn't change your payment.I recommend you speak with your lender so they can explain this to you.
