How much do you set aside for Maint/CapEx/Vac. (NOT Percentage!)

[Gaspare U.]

I know a lot of people on MF use anywhere from 20-25% set aside between Vac, Maint and CapEx (trio) which is fine. My question is, is there a level you are comfortable setting aside? Let me explain via an example.

Let's say you purchase a multi fam and the Gross annual income is $100k. So you should set $22k per year for this trio. After 3 years you have accumulated ~18k (22k minus capital spent on the trio per year) at what point do you stop adding to this "fund"?

I originally was thinking after $30k (let's assume for the most expensive cost replacements: a roof, kitchen, parking lot, etc.) anything above that would be allocated elsewhere (reduce loan, investor debt, income, etc). And as things come to surface let's say a problem tenant. In this example, it costs you $4k in lost rent, legal fees, apartment clean up and  paint. That fund is now reduced to $26k. You again begin to build that fund up to $30k.

1. 1. Is there a professional term for this "fund"?
2. 2. How do you judge exactly how much cash you set aside for this trio?
3. 3. Is there a term for this "trio"

I rather use the correct terminology, so thank in advance for corrections. If I'm not explaining myself clearly please let me know I'll try and re-word it.

Thanks in advance!
