@Michael Farrugia there are institutional lenders that will funds these deal for you with 25-30% down.  

Still, LendingHome could be a good source of bridge funds to get the property into your name with slightly more lax criteria than most traditional banks and lending institutions without crazy-high rates and fees.

It seems to me a bank or other financial institution won't look at anyone who does not already have some buildings, but you can't get buildings before you get the money.

Even if you get the secret or discounted rate, if you only get rates from one financial institution, you may still be paying a premium compared to other lenders.Suggest some good brokers who can help me with mortgage renewal in Canada.

By lining up LTR financing, you are stepping into the more institutional world, but honestly, you should not bother going through the hassle of paying anything until you are ready to actually close on a deal. 

However, if it's a larger bank/institution, you'd likely just have an agreement to pay the mortgage to the seller and they would need to turn around and pay the bank.

Google stock has 1,000s of well educated analysts running numbers on its value, large commercial or residential properties are looked at by dozens if not more institutional investors with entire divisions dedicated to determining the value of an investment while 4-plex or smaller is full of inexperienced or uneducated investors.  

I want to be able to lock down a deal then go raise capitol via my investors while I  sort out the lending institution.

My questions is has anyone used Sofi for a major purchase besides hard money lender/institution or conventional bank?

You can institute the punitive measures which should be in your lease for that breach such as a fine, etc.
