@Donny Widjaja we usually budget somewhere between $200-$400 per unit in reserves, because, well, you just never know when you're going to need to take down a tree, replace a leaking roof, or service an old boiler. 

My most recent deal which funded last month was purchased for $53K, rehabbed for $1,500 (trimmed trees) and sold 5 days later for $88,700. 

I leave bushes and trees and maybe a couple plants in the rock up front. 3.

If the owner can’t stomach tree trimming and painting costs, there are likely man larger costs they can’t stomach also.

either way that 3day/sales event helped me make a decision that flipping or wholesaling is not my cup of tea and decided to start buying rental properties .    

I have also had dogs chew the bark off of trees.

What, no crane tracker in my backyard to take down 4 trees?

That is a huge tree.  

Not to beat a dead horse, because, well, PETA :) But along the lines of my previous post, just YESTERDAY I posted an add to have some trees we'd purchased planted.  

The expenses you need to know are cost of yard mowing, water for watering, cost of fertilizing and treating trees, cost of snow removal, any utilities not billed separately to each tenant, (water in my case), utilities to common areas, then standard costs of mtg payment, taxes, insurance, vacancy projection costs, and maintenance and Cap ex.
