Can you give the forum a few numbers on your existing properties, including estimated values, current loan balances, current rent on the duplex and expected rent on the SFH?

Here’s how I’m currently thinking about it:The interest rate on my existing property is 3.5%, so I’d like to maintain that rate rather than refinancing the entire loan.

I recently looked at an existing STR, but either the seller did not track the expenses or they did not want to provide them. 

Why are you starting a new thread when you posted this same stuff on an existing thread? 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

As you grow your portfolio, keep an eye out for lenders who offer low down payment options for investors or those that allow leveraging the equity from your existing properties to fund new ones. 

Check with an architect first to be sure you can fit your vision into the existing lot, as it's zoned currently.

I wouldn't touch Franklinton with a 10' pole on the existing inventory side. gravity 2 is being auctioned and sold by the developer the area didn't support office developer lost millions:https://www.bizjournals.com/columbus/news/2024/12/19/gravity...linden I agree on if you can get a good deal. super fast appreciation. small homes, close to downtown, you can look at year over year and it's going up fast but also fast to change. any urban adjacent neighborhood is going to be good. 

At the moment I have only been looking at SF and 2-4 MF I would not mind either just making the numbers work is hard. 2-4 MF are hard to find in the Las Cruces market right now but they exist.
