By the way my last local purchase was dec 2021 which was before rates started increasing (just a few months before, i had good timing - when the fed states they are going to be raising rates, it is a good idea to believe rates may go up).  

I'm considering increasing that last one as property values go up.

And lastly, I search FunishedFinder listings nearby, find comparable properties, and track the listed rent for a few months (does it increase, decrease?).

As time goes on, I suspect that we'll probably see more deals as delinquencies increase with a worsening economy and we want to be in a position to participate if and when that happens.

Sold with extra lot for value increase Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Quote from @Lionel Quiambao:  ... and maybe throw in the option for the tenant for more speed at an increased rent to cover the additional payment. 

I agree with @Jonathan Greene that the question is vague, so my advice will have to be as well.The short answer: MTRs are real estate, so just like all real estate, any place that can long-term-rent cash flow with increasing jobs/population can be a suitable site to purchase. 

On the other hand, investing in some repairs (if financially feasible) might significantly increase the property's market value.Remember, each property is unique, and what works for one might not work for another.

There is nothing illegal about Subto when it is done legally, as you infer.Actually, Due on Sale is a result of banks calling loans due back in the 70's and 80's, simply because interest rates had increased and other spurious events like that.

Overall nationwide cap rates are rising because of interest rate increases.
