I'd probably have sufficient funds available to add either another Duplex or 2 more SF later this year. 

I have a once triplex converted to a duplex that I’m turning back into a triplex . hope that didn’t get too confusing.So I’m trying to figure out the best way to supply all 3 units with sufficient hot water in the most economical way of course.

As someone with vast rental experience in Austin, TX (and a resident of Dayton), I would suggest really conducting a PFS (Personal Financial Statement) ahead of time - if not already done - in order to better assess your purchasing capabilities, then we can dive deeper into the creative methods.Connect with me to discuss when it would be a good time to talk.

(Again, check your local laws to make sure this is sufficient.)Also - unless the laws under which you operate say otherwise - you are "notfying" them of the increase. 

Domicile: WA State (income tax free)Property location (Texas): (income tax free)LT gains + Depreciation recapture ~ $300k on a $500k income property ~effective / average tax rate = 12% for past umpteen yrs (relatively low income, avoiding IRMAA and doing Roth rolls (no 'realized' income, just transferring from tIRA to Roth = vast majority of annual MAGI income)In the end (coming soon, ~17 yrs) ALL remaining estate will go to charities / Charitable Foundation / DAF.

I know this is bogus and I have sufficient documentation to prove so I am not extremely worried about that.

If the cost is high and you're not getting sufficient ROI, it might not be worth the additional debt or investment.Tenant Considerations: Frequent repairs and maintenance requests from your tenant indicate that the property might be challenging to maintain.

If there's sufficient equity in any of your properties, it's worth considering the potential returns from deploying that capital elsewhere.

FHA will undergo a self-sufficiency test for 3-4 unit properties which can make it hard to qualify for depending on the scenario.
