You've listed the "big three", and those are all that are needed for most MTRs, especially if you have a limited number of doors in an area.

What I can share is that the risk-reward will not be worth it as a 'newbie' due to your limited capital and inability to actively manage your properties. 

I've used an online designer before, you send her photos, measurements of the room and existing furniture, and your budget and she presents you with design options and the links to buy!

We have offered to allow her to pay a reduced rent for the first few months as well but I am worried that may create some sort of limit on how much we can raise the rent on her in the future.

Properties below this threshold present additional risks and more limited borrowing options.7.

It also offers a chance to shift into something more passive, reducing the hands-on management that seems to be more of a hassle now that you’ve moved.That said, the rental income potential from your properties is worth noting, but there’s a limit to how much you can boost your cash flow, especially after already making significant upgrades.

Most cities don’t want a mobile home park in their city limits because the tenants take more money out of the tax system than they contribute.

Do you offer 80% LTV on the full appraised value or is it limited to purchase price + repairs completed? 

 @Patrick Pan not all states take such measures, and you can ask a reputable tenant screening company in your area how that works.  

@Steven Rosenfeld On Goodegg, no direct interaction here; they seem to maybe have limited full cycle experience in the GP/syndicator role.
