This will also protect you from unforeseen costs, so you will still make money if something goes wrong.

I also keep a reserve fund for all those unforeseen happenings and use any remainder amount to purchase the next property Cash always has to be moving otherwise it's of no use in increasing your wealth - unless of course you have a stock pile of gold. :) 

There are unforeseen problems on every plan and they cost adds up rapidly.  

This covers the down payment dilemma - what happens when a problem with the work, whether due to workmanship or unforeseen circumstances arises?

So in months like January of this year and April of this year I can see where I was close to, or under budget and months like March where I had unforeseen expenses that came up.

Cash flow management is an important part of the business. don't overleverage yourself to the point where one unforeseen makes you go bankrupt. ideally, if you want the tenant to leave so you can rehab and refinance you either buy them out of the lease, or put them in a hotel while you refinance, but that's not something you can depend on 100%.

Not because you didn't do it right, but simply because unforeseen things will often pop up.If you are on such a tight budget, I would be worried you WOULD end up left without enough to finish repairs.Be careful!

You will run into many unforeseen expenses.

I'm currently operating an AIRBNB/short-term furnished rental in Avondale/32205 I Do Not Want To Sell, my son and I put a lot of pride in the property, and it has so much appreciation potential -- but due to unforeseen circumstances, my credit score has dropped and now my refi options are dreadful - (30yr 7% int, 2½ pts, ridiculous closing fees,10k early payoff penalty). 

@Michael Plaks"Unforeseen circumstances" is surprising taxpayer friendly.
