I don't think it's wise to try this until you have proven experience and a solid partnership agreement.It's OK to scale slowly.

@Chris Mason thanks for the info regarding the loan options for ADUs.

@Vincent Cavalieri Happy to connect.

I am pretty sure you can not do a 1031 and use the proceeds to do anything to a primary residence.

So, your focus may need to pivot from high rental cash flow to little to no cash flow as a rental with an appreciation upside.I would recommend taking your $150K to $200K and securing a solid equity position in something that will cover its expenses and maybe provide a small cash flow, but then is poised to appreciate nicely over the course of the next several years. 

This seems to follow the general overall trend of lower cost areas winning at the expense of those with a high costs of living.

Let's use an example of replacing a leaking kitchen faucet (assuming it can't be repaired):You can easily find out how much the materials are by going to the Home Depot website and picking one out.For labor we Googled, "How long does it take to replace a kitchen faucet" and this is the answer we got:AI Overview: Replacing a kitchen faucet can take 30 minutes to several hours, depending on the faucet's complexity and whether you're doing it yourself.

I've been doing some light reading, and it sounds like refinancing that property and using the proceeds to reinvest elsewhere might be a better option. 

If your mental health is so fractured that you can't go to an Open House on a four-family down the block from you, that is something to focus on first.

I used Smarter Contact last year, and there is big issue they need to fix.
