@Steve Maye thanks for the detail, I think we asked that because you were interested in knowing if what you did was smart or not and since we did not have the full picture I think @Joe Villenueve and I wanted to have more detail to give an opinion.
From the number you provided I think it was a good investment.
A couple of things you will need for your math to be realistic long term is:
1. Estimate for average repair costs going forward
2. Vacancy rate
3. Commissions for realtor
4. Umbrella policy if you are considering to get this in the future
As to your question on a next move, I would give serious consideration to the following:
1. Get some debt maybe buying 2 properties with 50% financing on these
2. Consider what was the increase in property prices since you bought the first home vs the increases in rent in the same period. My guess would be appreciation was faster than rental increases but it can vary market to market.
3. Prioritize buying discounted properties probably REOs but do a thorough review of property condition and assessment of costs of repairs. If you look at recent comparable sales and are able to see the pictures of the property sold and sq ft you might get an idea of the discount you are getting. Also Freddie and Fannie have very good programs for investors with very high leverage (I bought at 90%LTV with 4.375% rate)
To expand on point 1 the logic for getting some debt is the following:
1. if your return on a cash purchase is 7% a 50% leverage at 5% APR 30 yrs fixed will increase your return to 9% of the cash invested.
2. The appreciation play is double as you have exposure to twice the assets (but in the same way it plays against in the downside). Your inflation hedge is somehow better also as rentals are somehow correlated to inflation and since your mortgage payment does not change (use only fixed rate non recourse, I personally prefer 30yr fixed loans) this results that the weight of interest payments over time tend to be minimized as rents increase but payment remains constant.
In summary I think you did the right purchase and got the correct returns but you might consider some leverage. you must feel comfortable with having to make monthly payments every month.
all the best.
