There will always be more and more ways to spend money.Start by reducing expenses.  

Identifying which risk you are wanting to mitigate will actually help point you in the direction of how to reduce it.  

Property not used for primary residence is reduced in the maximum amounts loaned against them.   

I work at the local community college where I started a sustainability/construction/renewable energy/energy efficiency program and teach some courses.

I have to replace the AC unit because the builder used a CHEAPO brand, but I got the seller to reduce the price by the cost of the AC Unit. 

At 100 a month increase you are talking 41 months ( a little over 3 1/2 years) to get a positive of the 100 a month back.Now increasing rents and reducing expenses will usually grow your equity and resale price.

Well here's what I figured out, using the first link as an example ($52k triplex, assuming 1 unit is vacant):-TaxesIndianapolis, marion county, 3.13% or $1627 a year, though there's a homeowner deduction that reduces it by half If I live in the house.

These 2 factors will also reduce your returns.Thanks for sharing!

Originally posted by @Josh Mitchell: Water, Heat, Gas, pool, common insurance, scavenger, landscaping, elevator, tennis court, basketball court, parking, storage, laundry, clubhouse, snow removal, exterior maitenance, security door locksSome of the items you list will reduce your costs but many just go to pay for luxury items for the tenant.  

Usually, the cost savings they see from reduced time spent on rent collection, reconciliation, and accounting well outweighs the cost of PayNearMe.
