I would think duplex property might result in lower rent than a detached single family property.

Living in a single family home now.

Every single lender out there wants to fund a project but they don't want to give you money up front.

One other adjustment I would like to make that is currently on the lease is the lease says "owner pays water for both units" with me being a single and them being a family I feel it's fair for them to pay for their own water bill because they're naturally going to use a lot more water than me.

I'll agree with @Ashish Acharya here: if you're wanting to sell the property primarily as a way to get some tax-free cash, then yes, sell within three years after moving and you qualify for the $250k(single)/$500k(married) Sec 121 exemption.

But heck, with a single income, that was my only option.My intension is to use my first BRRR to launch and do more deals, with the goal of building a rental portfolio of long term passive income.I'm excited to show you the numbers and photos. 

ANYTHING.I grew up with nothing, came from a poor home of a single mom who worked hard labor her whole life to provide me the opportunists I have now.

My wife and I have one single family rental already, and I'm looking to learn more and expand our real estate adventure!

Of course, the more details you share about the property the better, so here's a generic outline to make sure we get all the necessary info to evaluate what to expect:Property Type: (Condo, Single Family House, Multifamily Property)Total Doors:Purchase Price:Year Bought: (Buying at bottom of market obviously makes for more cashflow today)Financing: (Cash purchase, financed with percentage down, lease option, etc.)How You Found Property: (MLS, Off-market, Wholesaler, Foreclosure, REO, etc.)Property & Neighborhood Rating: (A-F, 1 to 10, neighborhood quality and condition of property)Net Cashflow Per Door:Cap Rate, CoC, Appreciation, Etc.: (Any other metrics or ROI figures you think are important to the deal)You can either answer in this format or write a paragraph or two including all the details.

However, if it was clear at the start that you were offering a reduced rate for single person occupancy and that is changing now, then you can renegotiate the terms of the lease.
