My wife not comfortable putting our house as equity, therefore we are utilizing other options to fund investment properties. 

As for the decision, it's really tough for any of us to say without knowing your goals, your situation and the numbers on this particular house.

I have considered it but I keep things at a flat rate for the exact reasons you stated.I want people to get the exact price when they stay at our lake house.

We recently relocated from our primary residence to a rental property ourselves (we recently welcomed a baby, and our house no longer accommodated our evolving needs).

I've done this on one house in order to cut costs - since then, I've added a meter with the utility company but it's a good workaround for the short term. 

It is a corporate housing arbitrage mentoring program.I'm about to sign up but wanted to do my due diligence I want to check with people here if this is legit and if the program is worth the money they as asking for.

A house that's similar, but 10% larger than another usually isn't worth 10% more.

For residential multifamily properties (1 - 4 units), can you use a home warranty to take care of the repair costs associated with rentals?

@Michael Daniel Ultimately, it's all about confirming what the housing authority pays.

Hopefully you already worked this out.Aside from HML, there's also an option to do a live-in-flip, where you live in the house for a year and renovate it slowly.
