If they are squatters you will have to go through an ejectment which is lengthier and more expensive than an eviction.

Target rent is 2200, my expenses will be around 2050, so cash flow of 150 (not including vacancy).  

@Collin H. are you seeing your better units (location, amenities, decor, etc) outperform their numbers YoY and the opposite true to average and below average units?

I am seeking advice on making my offer compelling but also making sure I'm not missing anything/potential expenses.

@Yoav Gilad, this sounds very sketchy and somewhat manipulative, but is there a site or resource for finding property owners with overdue medical bills or expenses?

Real estate is expensive, and most of us do need leverage to purchase properties. 

Other closing expenses usually aren't deductible.

When I buy a property  how much can I deduct in average from that purchase for that year or what thing related to that purchase can be deducted.. ( example: the down payment?)

The difference in rent is about $300 with the lower rent being in the less expensive home that has not increased a lot in price, the other was almost double the price and has more than doubled in price (that market is nuts)...so I get a less rent relative to the price of the home, but the increase in the value of the home more than makes up for it.

Total expenses: $3,850.Each unit rents for $1,000 a month.
