Personally, I like to keep the equivalent of my insurance premium in reserves at all times just in case, regardless of my access to credit; but I don't think that's what you're asking.If I understand you correctly, you're not at that stage yet.

Town says I will need to install them but If I am reading code correctly it should only apply to new construction buildings over 4 units. https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXX/Chapter148/Section26iThey also don't seem to give specifics on what "substantially renovated is" But a court case ruling gave this clarification: “… in order to require the installation of sprinklers in an existing multi-unit residential building, the rehabilitation must be so substantial that the physical structure is rendered ‘the equivalent of new construction,’ i.e., in essence as good as new.

Unfortunately I will never refer to these large companies again since it is the equivalent of hiring Dollar Tree to manage your investment.

However, renter's insurance isn't the equivalent of Aircover anyway.

I have read that you must have the equivalent of 6 months rent in reserves (not a problem) when looking for a new property if you are keeping one as a rental and it has not been rented for 2 years.

If you think about it, 5% - 6% tax free growth may be equivalent to an 8% - 10% gross return in the stock market...but then you have expense ratios, advisory fees and capital gains taxes taken off the top bringing your net returns much lower.2.)

They also cover you incase the property gets damage and it can't be rented for up to a year or at least the equivalent of the rent value for a year.

If you put your funds in a muni market fund, you can get it equivalently tax free and keep your tax structure low.Also, the "buy and hold" strategy really does include "selling." 

😂 Instead of investing in my TSP (401K equivalent), I reduced my contribution to the minimum where I would still receive the full employer match, which in my case was 5%.

It is my opinion your goal should be to live there with a complete initial cost less than what you would be charged to rent an equivalent unit.
