I'm willing to bet that there are more instances of contractors burning investors than the other way around.

Are there specific advantages or potential pitfalls I should consider when structuring these activities through my LLC?

There is also a lot of activity in my facebook group, and it's all about MTR.

You are betting too much on the refinance portion if you try to BRRRR with hard money.

If your goal is to offset your mortgage with a house hack then Lowell would be a good bet, but if you're looking for a longer term appreciation play then the areas closer to the city would be better, although the offset from cashflow may be lower than what you're looking for.A good step for you would be to dig into specific areas more as @Lien Vuong noted above.

If you are having that much activity but cannot find the right tenant than you will want to lower the price just slightly to entice better tenants OR you can relax on your qualifications.

PG's are worthless those that have PGs that are worth anything dont need gap funding they have the cash.this is a play for folks you know well .. not for internet facebook BP etc.. people that do this do it because they know you like you trust you and think your a good operator.Public has to many other choices that are much safer bet.. its not always about ROI with those with money..

However, we are seeing far more activity in Nova Scotia for both investors and clients.

This means that if you do not want something as active as value adds, you need to be patient.  

For those that don't have the time or resources it's a great way to passively invest.Now if you want to be more active there are agents who can help you scale with the right teams in place.
