I manage around 400 rentals with 14 years of experience and have never been sued once.

Not having experience qualifying prospects I would think that the leads you would get from here, if any, would be..... challenging. 

Definitely ask if they have experience with this. 

I'm wondering what people's best experiences with low flow are, reliability, durability, best brands, savings seen, and if I should avoid the extreme low gpf toilets for water savings (0.6-0.8 gpf).

One of our parks is 60% POH and in my experience the only way that park pencils as well as it does is to get through all the major repairs, get the homes 'right' and then keep them 'right'. 

It’s a smart move, especially since it ties in with your goal of saving for your first investment.For skills, you probably already have a good foundation with your sales experience—things like communication, organization, and dealing with clients are all super valuable.

Confirm that the provider has experience with the particular investments in which you intend to invest your retirement funds as you very likely will have questions in terms of the mechanics (e.g. how do you invest in real estate, etc.).4.

I would not take advice about a market from someone without any experience in that market. 

Those deals are rare and starting off with such a good experience is amazing. 

Based on my experience of running properties, even if the build were to cost you as much as $600k but you could generate $125k/year, you'd be very happy with that investment.
