We have to fix the wild out of control form of math first , then move forward to then control the rest of it.For example: commercial retail taxes needs to be taxed per foot-per proximity to corners and/or car counts, amount of parking, etc.

Only take classes that count towards your degree.

They are counting on the fact that out of town investors have little recourse, however, the growing number of investors who have been scammed are banding together and will seek legal recourse.  

I think the commute to Waltham would grate on you over time though, and TBH there’s a lot more economic activity and jobs in Mass than RI.If you engage a Realtor you will, pretty much by definition, be paying market value (with rare exceptions you shouldn’t count on being able to find on demand).

From a developer's perspective, they generally like to work in areas where they can count on support from the local government. 

Normally lenders will only take 75% of the rent you collect and count that against your debt to income ratio for the next loan.

Tarps or other temporary structures do not count toward required covered parking spaces."

The question is, do I add these additional amounts of investment that are from my pocket not my tenants in as part of the "Beginning Investment" number so that I'm not inflating my ROI or do I count it as Ending Investment because I could have just put that same money in the stock market or elsewhere instead of the rental if I didn't have it and it's still investment?

@Collette Douglas I don't know about the Armed Forces aspect of that regulation, but my guess based on how it's worded would be that it applies to the 183 days part only - that the property would still have to be your primary residence, just if you are on active duty and outside the state for that reason, then you wouldn't have to count your days.As for the 2 years, I don't believe it's simply owning for 2 years, but that it's occupying it personally (as your primary residence) for 2 out of the last 5 years.
