Sounds like you have an unscrupulous lender who purposefully underestimated title costs.

With the market how it is you may still have limited capacity to negotiate with the seller if you are looking at properties listed on the MLS though, unless they are significantly overpriced to begin with.See below for some notes I had written for my own purposes when I was researching Lynn.

to me there are credit lines and then there are credit lines.IE the vast majority have a heloc on their personal home or maybe a rental.. with a credit union local bank big bank etc.then you have credit Lines that are unsecured for business purposes .I have not heard of credit lines being frozen yet.. but I sure saw it a ton in the GFC.. and very few folks that get them on their personal resi or a rental.. actually read the fine print and therefor are shocked when they go to access their heloc for this deal they want and its frozen.our facilities are on one year terms with a mandatory 30 day rest per 12 months.. its been that way for me for 20 some years LOL.. mine are unsecured and of decent size i am not talking 50 to 100k..

I'm in the UK which has a complex situation with US taxes, but if I'm reading this below website correctly you may have an easier time if you are treated as a non-resident Australian for tax purposes.
