The benefit to me is if there is a deadbeat, the deadbeat is limited to one room (~$400) instead of the whole unit.

Let's chat in private as I do not want to seem to solicit to anyone and everyone on a public forum but in general our innovate model that installs in applications where plumbing is not separated probably runs $200-300 per apartment unit ($400-600 for an entire duplex).

I have wonderful tenants renting out his house now, just lucked out by picking the best applicants even with minimal screening.

You can identify as many properties as you like, with no total value limit, as long as you purchase 95% of that value.

@Grant Rothenburger thank you, to keep from limiting myself, im open to small or larger sized properties.

(b) Plumbing facilities which conformed to applicable law when installed and which are maintained in good working order.

The benefits for you are that you have limited risk if something happens to the property it's less risk for you personally they go after the LLC unless the problem was your negligence and then they can go after you.

Design Development  Construction DocumentsThe design requirements will include but not limited to:   Installation of new plumbing and electrical systems with separate electric metering for each unit  New gas top –vent gravity natural gas wall furnace and air conditioning system.

The difference in cost to the tenant to have higher limits is typically very small. 

Other than that our experience and knowledge of the area is limited.
