Should I purchase the home next to mine?

[Michael Phillips]

Hey everyone, I have a purchase conundrum on my hands... I currently have a 2 unit duplex in Echo Park CA that I purchased in 2018 for around $1 mil, renovated for another $75k. It has been fully rented at $3k per unit for a year now, I manage it myself and things feel somewhat steady. Both of my neighbors are rental properties and one of them is going on the market next month. It is a SFR for around $600k that is renting around $3k like my units and will be delivered vacant and in updated condition to the buyer. I was planning on purchasing another property next year but am wondering if this might be something worth stretching for. It of course depends on final sale price, actual condition, etc... but it seems like there could be value in having properties that share a fence line from an oversight perspective and event in the future potentially an exit opportunity (especially considering my current property has two APNs with the house on one and backyard on another). Is there long term value in locking up three contiguous lots or should I wait until I had planned to jump?
