These numbers will drive the market prices duplex/quad/apartment buildings as every investor has *somewhat similar* goals and objectives.I would bring a few deals to the next DFW BP meet up and pitch them to some of the folks there who have done this before.

Hi Stu Jermaine here,  Stu that is not called a tenant that is called your buddy staying with you and pitching in by paying the utilities.Nobody stay for free(ooouuu I hate even saying that word,,, free) but what you should do is have your "buddy" pay you and you pay the utilities

The potential for overhead leaks increases the more mechanical joints you have.One way to minimize that is to not have any joints at all in the attic. 

I'd begin checking them out with the state finance department in the state they are organized in.Also, beware of investing in a note with other investors, taking a fractionalized interest, there are many out there in the note business that know more about marketing a product than they do the product, you'll find overstated valuations of collateral to minimize the LTV implying a margin of safety and saying everyone is covered, that may not be the case as I've never seen a dollar split 3 ways evenly.

Otherwise, its on you.BUT in the long haul, that will be a minimal expense and covering it even though the problem MAY be their fault might go a long way in tenant/landlord relations.And the final trick - just remove it!

The pitch went something like this:  "We have a long list of vetted, quality contractors that work exclusively for our investors.  

Lenders pitch 25% over 20% because the rates are generally way better.

A friend and small multi-family client of mine has start-up they've been pitching to angels and VC's, and I wanted to run it by the BP community of big MF investors and property managers. 

The tenants are all professional (example Apple engineer), maintenance cost is negligible as a percent of rent, vacancy is minimal (I got the tenant within one week of listing), rents rise annually and I can self manage so no PM costs.

One thing to keep in mind with short term rentals is in my opinion your number one goal should be to minimize vacancy.
