I am guessing I made a mistake, because now I get multiple calls a day from mostly three different lenders: Rocket Mortgage, Loan Depot and I am not sure what the third is.They feel like salesmen, is there a catch with using them vs using a small bank or an established brick and mortar bank like BoA?

Most of the time, your Chase, BOA, Citi type banks will not be interested, but always worth a call too.

As of now, most of the banks I've contacted simply don't have a construction loan product, but perhaps I shouldn't be talking to BoA and Wells Fargo for this.Any help would be greatly appreciated!

My lender is BOA. 

I had a conversation with my Business rep from BOA.

BOA has the best transfer options of any bank that I’ve come across.

Then Assigned REC 2009 to Assignee; MERS, a Delaware Corp. its successors or assigns, as nominee for CitiMortgage, Inc. and then FURTHER Assigned numerous times subsequently thereafter with the most recent Assignment REC 7-2023Its been non-performing for years and its a residential home that is occupied (presumably by the original Note payor) Since You Referenced it - AND for the benefit of others here is a Snippet Article on the BOA Vs Greenleaf Maine Court Decision - Titled Maine's Greenleaf Decision Creates Mortgage "Insecurity" for MERS https://casetext.com/analysis/maines-greenleaf-decision-crea...

Heard about robo-signing, and BoA foreclosure mess, and how lawyers/defaulters are getting more embolded to resist and sue the foreclosing bank.Does title insurance cover me in case the previous owner sues for "improper foreclosure process" used by US bank, if any?

Leaning towards switch to BoA or Wells Fargo, but wanted to see if anyone had experience with them or possibly a better suggestion?

Our biggest problem was that Bank of America, or perhaps just the person handling our loan at BOA, either didn't know what she was doing, didn't care, or both.
