Our business model includes a month of vacancy every year, but in practice it usually only ends up being a week or so every 2-3 years for each unit (we don't turn over every year).

According to Case-Shiller data (https://fred.stlouisfed.org/series/LXXRSA), Los Angeles home prices have had a compound growth rate of just under 5% since 1987 (median price of $60K to median price of about $280K in 32 years).That's about the same as the increase in median home prices across the entire US in that same time period (https://fred.stlouisfed.org/series/MSPUS).So, if appreciation is about the same over time, but cash flow is less, what models are you using to determine that the ROI in LA would far exceed that of other places in the US given the likely greater cash flow in other areas?

@Cameron HolcombeTry to become the first wholesaler who conducts and honest,truthful,ethical business model.

After I reach about 25 doors, I'm going to re-evaluate my model however.Anyway, best of luck and if there's anything else I can answer for you, I'm happy to do so.

IE a lot that can be sold on the open market is one of our go two models.. 

The tenant has been a model tenant for over 5 years.

Its definitely a model that would be typically used in a student rental market, but I would have never thought to use it for career schools such as a military occupational specialty school.

I have an Excel model that spits out cash on cash return and yield (includes mortgage paydown) both come out with a significantly higher rate of return on a 30 year then a 15 year.

I ultimately decided that I didn't like the business model enough.

You need to define what your business model is before anyone can answer your question
