Well I am still very much a novice and only just now preparing to close on my first property. It is a SFH.
I grew up in the KC area and know it fairly well. I still have family and connections there so that is a huge plus. My brother is a mortgage banker, one of his best friends is a PM who runs a pretty solid looking company, and his wife is my real estate agent. It made putting a team together a lot more doable. Since that time I have connected with a very solid inspection company who will really tell you the ins and outs of the property you are getting. Also connected with a good handyman and a good pest control company.
As for numbers, the place we got was right about 70k. The estimated rent is projected to be between $850-950, and I think the higher figure is more realistic honestly. So after all expenses we are looking at just slightly under $200.00 per month in cash flow. I'd be happy with $100.00 however on our first property.
