Honestly, this is a little out of my wheelhouse, I've never wholesaled a deal, so take my advice on this with a grain of salt please.

I'm wondering whether the new tax law, with the limitations on SALT deductions and limitations on mortgage interest deductions, will cause the retail single family home market around Boston to soften......I believe this is happening in the suburban areas around NYC.

My opinion can come with grains of salt, but it's because of one thing or another or where they are limited, but you won't see that until actually doing a deal with them (whoever it is). 

and then refinance once it is 90% or more occupied.Anything the broker posts has to be taken with a grain of salt as they are trying to sell the property.

Auction.com has an estimated ARV of $600k, but we are taking that number with a huge grain of salt since any comps close by seem to be more around mid 500s.A quick plus delta of the situation as we see it:+ great location (corner lot, water front on a small lake, good neighborhood with very nice neighboring properties, close to main road).+ REO with a motivated bank seller (assuming they will be dropping their minimum each time they put it up for auction?)

You’ll probably have to search using more non-traditional off-market approaches.And I’d look at Dallas and Salt Lake City first. 

I have been aggressively searching for my first multi-family unit property and live in the Salt Lake City, Utah market.

I always take negative reviews with a grain of salt. 

They are very honest,, elderly couple on SS, he does shovel some sidewalk at no charge and salt it.   ...thoughts? 

Where I think this deal starts to look less attractive is:There's no depreciation on land (I don't know Canadian tax laws, so take this with a grain of salt).
