Honestly, with a glaring error that big, I'd be inclined to throw this paperwork away and start from scratch, fresh.

It was freshly painted, rennovated and clean.  

From your perspective what are the best crowdfunding platforms?  

Since surveys not usually recorded in the public records, any survey you locate is of little use from a purchase perspective other than for you to see what "may" be the property boundary lines and possible easements. 

The dog duplex could be profitable if the market is right (pet ownership is over 50% in many areas, yet fewer places allow them)...I would either try and market the duplex as  a dog-friendly unit (with the separate yards) and give full barking disclosure and even invite the applicants to come by at various times to test the noise themselves; or (especially if my dog friendly marketing wasn't working) I would cycle the existing tenant out, remodel and go with fresh tenants of your own choosing.Best of Luck....

Perhaps a conversation on perspective is in order.

I have only looked into HUD from an investor perspective.

Do you have any thoughts on which island is best from an investor's perspective?  

From another perspective, though, prices are higher ... so lower rates on higher prices may be more expensive in dollar amounts, as I suspect would be the case in many markets (yours and mine, for example) for a mortgage payment at 15% in the 80's vs the mortgage payment at 4% for the same exact property today, even after adjusting for inflation.

From a realtor's perspective, doing a lot of CMAs (time), and then showing a lot of houses (gas money and more time), and writing a lot of lowball offers (more time) that most likely won't be accepted (we all know it's a numbers game) means a lot of effort with the final result - if they're lucky - of scoring a very low purchase price property and getting a tiny commission that they divide with their brokerage.
