Great question! I get this question from a lot of clients, and it can really come down to looking at just a couple things, and a couple of questions you have to ask yourself of what your financial goals are long term.
1. What is your cash on cash return for the 1, and what is it for the 2? I.E. after expenses, what are you cash flowing on the property, and what is the total percent of the money you invested you can expect back each year from that cash flow.
2. What is the average appreciation for the properties in that area? Or, to get even more gradual, what would be the average appreciation for the type of properties you're looking at? Your realtor should be able to help you with this.
3. Lastly, based off of these 2 questions, what is your Net Worth ROI? Or, your cash on cash return, plus your appreciation in these homes should be able to give you your answer.
More times than not, you are going to see a better ROI on investing in multiple properties. And it really depends if you'd sell these properties down the road, refinance them to buy more, etc.
You should also talk to your Realtor about what sellers are willing to offer in your market when it comes to temporary buy downs the seller is willing to cover via a seller credit. That is how I've been helping my buyers stomach these rates and buying them time to hopefully refinance if and when rates go back down. Never a guarantee though.
Best of luck!
