I have about $150k cash on hand as well as I am planning to get a construction loan to cover the remaining cost of a duplex.

Property 1:Purchase price - $73,000Mortgage - NONE (Paid Cash)Monthly Rent - $875Monthly Profit - $580Property 2:Purchase price - $65,000Mortgage - NONE (Paid Cash)Monthly Rent - $950Monthly Profit - $750Property 3:Purchase Price - $107,500Mortgage - $80,625 Monthly Rent - $1300Monthly Profit - $435Current Cash Available - $110,000Current Available Equity - $96,500 Cumulative Total - $206,500The available equity was a HELOC loan that was given at 70% LTV so those are real numbers, they would be from property 1 and property 2.The reason im typing this is because I would like to know if there were any builders that could give a rough estimate of building cost per square foot in Kansas City area or suburbs.

And yes, a lot of PMs are charging low nightly rates while padding their own accounts with fees that you don't see much of.

We estimate that the basement will cost approximately $30,000.

Three units to maintain.Although I need to do the math, scenario 1 strikes me as more economical as there are shared costs gained with a multifamily property.

@Kathleen Park if you want the tenants to cover, just increase the monthly rent a bit at renewal to cover the cost.

I would tell you to get really, really smart on self-storage, mobile home parks, or something that can be run by a low-skilled employee and pretty hands-off. 

We were also looking at a TON of houses in the area so we knew this house was under what it should have costed.

You'll want to run some comps to be very aware of the pricing in the area and then it will help to have some construction costs in mind.

The projected rents on the low side if I rented out each of the 3 beds individually would be $1800/month.
