I'd love some recommendations for reputable lenders, online or otherwise.

MyRental by CoreLogic is another reputable platform.That said, the real gold is in pairing the credit/background check with income verification from the source—not just a paystub or PDF.

We had reached a point in our portfolio size where spreadsheet tracking and then filing taxes became too heavy of a lift for everyone and the cost of doing our tax return was getting hefty as well.That said, has anyone had any success figuring out how to link property loans from bank online portal successfully into your Quickbooks?

Does anyone recommend a good online school for this?  

Anyone use online resources for cost seg?

If it is a reputable firm with a website and great Google reviews, you can do the customary 50% down. 

We provide a list of local contacts, but it's only as good as the info they have online, so you'll have a place to start but expect to update some of that info as you are making your connections.Cons: This is all about relationships and people first, and I can't build those relationships for you.

Talk to a reputable lender and a local agent before making any moves and do whats best for your scenario. 

Once you determined that it can indeed help you, contact these BP experts, each one of them operates a reputable full-service cost segregation firm:  @Bernard Reisz, @Yonah Weiss, @Julio Gonzalez

Until that time, I am assuming that I am dealing with a reputable firm that is making the best of a bad situation.
