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.

Debt service is way up, revenue is generally down, down payments are way up, financing terms and costs are much worse.The time of fast scaling has passed, unless you're very creative. 

I am a long-term investor, but I also provide services to long-term investors, so my advice is biased toward that option.  

We know of a bunch of the servicers but curious of others have servicers they prefer.

It would be wise to rectify it before transfer of title so your starting off clean and hopefully won't have any issues when you go to sell down the road. 

Craig, I'd be happy to review your docs and deal for you and get you to a servicer.

The number of DSCR (Debt Service Coverage Ratio) loans a lender will offer can vary depending on the lender, your financial situation, and the property cash flow.

He gave me the owner's number (Jeff) and I called him on the spot, hoping to be able to offer my services to help him find and sell more homes in the neighborhood.

For example, to get up-to-date property tax data you would need to scrape every county's tax data website (thousands of different websites, data formats, issues, etc...) then aggregate and clean the data.

Are there specific lenders or servicers that are more likely to call these loans?
