I cannot comment on your BRRR strategy bc I'm not exactly sure what state offers properties in those price points but I'll talk about Boston:For your investment HELOC - have you tried commercial lenders?

If the buyer's strategy is to hold long term, and they are getting favorable interest or payment terms, and the value supports, offering more than ask isn't necessarily a bad thing for them.

I wish there was a strategy that takes no money and some do but you still need working capital for different things.

What's the exit strategy?

Not a good strategy. 

I filed a claim and my insurance company is estimating the damage currently.
