but it doesn't actually have any consequence other than tacking on extra fees to the property tax bill.

While rehabbing, I spent a little extra money fixing things that could potentially cause problems down the line.  

If you're in a slower market, I've seen anywhere from $1,000 to an extra 1% generate interest. 

One of those risks is a bit much for my taste, but two is simply too much.Take your extra 25k, and put that into an additional property.

If there was water pooling in your neighborhood with all the rain and offshore winds pushing the tides in and your property is not much higher than theirs, then I would definitely consider additional flood insurance, which won't be that expensive if you are not in a flood zone, except, of course, for that $250 annual surcharge they just added for investment properties.Also, I actually do add earthquake insurance on my Virginia property as it is only like $20 extra per year and after that scare a few years back and seeing some damage to a relative's home nearby, I thought it prudent.     

Upstairs tenant buyer pays option consideration = 2k+, rent is $850/mo with $300/mo as rent credit (tenant pays extra $200/mo, I chip in $100/mo rent credit).

It will cost you a few extra dollars, but you will have that added corporate layer between you and the temp. 

I only have 2k in my savings account because I dump my extra on credit card balances and paying extra principal on other loans and put a little into savings.

A simple zoning change (the city will almost always approve down zoning) will net you a few extra $100kIn Milwaukee I am way more open to it, but again the area I buy in has a high concentration of 2-4 unit properties so it is socially acceptable to live in an apartment vs a house and a SFH only rents for $100-$200 more

A lot of extra unnecessary costs.
