Most likely trying to find a sucker to buy this and take over the costly legal battle they are entailed in.So next time someone is like "yeah just get a deed in lieu at closing", think twice about that.Actually, I use the deed in lieu.  

@Dhruv Patel I believe you are getting ahead of yourself....Where in the US are you all-in (land acquisition, soft costs, hard construction) on new construction multi-family for $100/ft.

I have "XXXX" of debts every month, and make "XXXX" every two weeks.That will find the cost of duplex you need, though you may need to verify it is using current FHA guidelines as they have changed recently, so make sure you use that. 

To qualify for a loan, focus on having a credit score of at least 620 (or 580 for FHA loans), keeping your total monthly debt under 43% of your income, and saving enough for a down payment and closing costs—about 5-10% of the home's price in total.

Those situations go bad more often than not, costing you money and the friendship.

However, our tenant turned out to be problematic—late payments, issues that led to an eviction, and additional repair costs before we could relist the property for sale.Now, after months of making mortgage payments out of pocket, we finally have an offer.

In short, I can afford the additional $1100/mo cost of a second house, even until I rent it out.I have around $35K in HYSA and emergency funds that I could use for a down payment, but that's less than 20% which would be required for a conventional loan, assuming full purchase price.

.: I’m currently renovating a rental property and exploring ways to manage costs without compromising on quality.

I would guess an older home might be more cost to insure?

Obviously it will cost money, get some quotes.
