Additionally, I'm working with the RE Ally Property management team, who was able to find a tenant to rent at slightly above market rates without any vacancy.

Self managing should be easy, if not then that Realtor can probably help you with the rental side of it. 

Using a HELOC or home equity loan on your personal home could be a good option, especially if you can secure a low interest rate and manageable terms.

Cash flow can be great if you manage it well and keep occupancy rates high, but factor in the added costs of management, cleaning, and potential vacancy dips.

I am newly married and have a hefty mortgage myself, but I manage to save a decent amount of money realistically 10-15k a year I have been working as a construction worker as long as I have been working I am a mason by trade and even though moneys tight I know I will be a successful investor even in the current market.

Try interviewing at least three managers.1.

My role with this MF company is to manage the design, construction of the GC's and opening of the properties.

No syndication experience but there are about a dozen quality RV/Mobile home parks on market in Oregon, several with owner carry options that can be passiv-ish with management in place.

Do it very intentionally, not just for the sake of scaling up, but to get better quality or easier to manage properties that will replace lower quality or harder properties. 

There is also ease of management in having a handful of tradespeople that can deal with all my properties.
