I would not borrow from ANY lender I learned of over the internet unless I knwe personally people who had used them. 

I’m planning to do this for 3 multifamily properties all located in MA, each ranging from 2 to 4 units.

Do you have a price range you're targeting? 

The price range for the home would be $1M - $1.8M.Is there any way I could qualify for 3.5% down instead?

The market still has relatively low entry points compared to other major cities, making it possible to find multifamily properties like duplexes and triplexes in the price range you’re targeting.

The flat fee buyer agency fee reduces the amount of the buyer credit/refund, generally by $6,000 (although options range from $999 to $8999, depending on how much help the buyer wants from the agent).

However, because I am unable to make trips to scout locations or look at homes in person.

If you find a seller willing to carry a large note, that business is likely going to need a significant time and money investment from you post-close.Lesson 3️⃣ - It’s not that hard to be a good buyer.

Large syndication company, higher fees than most other syndicators.

need to get a better range on your ARV and not enough info to judge.
