If you were able to buy 2 duplexes as replacements then you would own MORE property so that any market appreciation is magnified and you might have MORE loan principle to pay down further building wealth that you don't see just by looking at cash-flow. 

So if your mortgage (principle and interest) and all the other expenses (taxes, insurance, and an maintenance reserve) totaled $2,000, but each side of the duplex will only rent for $1,000 in the current market - that isn't a good deal, right?  

So you don't have to figure out whether you can be objective and resist that human urge to want to help.

The seller sets the price higher than market price and between the down payment and any monthly principle payments the price eventually gets down to market price by the time the tenant could potentially buy the house.

@Isadore NelsonYour plan's financial analysis includes $48,000 mortgage payments, about $229 in monthly principle and interest, $200 in taxes and insurance, and $950 in rental revenue.

Do you have access to private equity investors or/and key principles and co-sponsors with a track record?

Must be occupied within 60 days of purchase, and must be considered the principle residence. 

Agreed, in principle.

I don't use those so I can't comment on them, but the principle is the same. 

Engaging with the community through forums and local meetups can also provide valuable insights and support from experienced investors.By setting clear objectives, you can create a roadmap that guides your decision-making process and keeps you focused on your ultimate aspirations.
