Basically you can afford -3500/month which equates to ~$500k if no rental income.  

So, because of this a lot of the "affordable" condos you will see in DFW have financial issues and you cannot get a mortgage loan on them, and have to pay cash. or, maybe get some sort of non conventional financing that is much more expensive requiring 25%+ down. 

I decided to purchase property in Pennsylvania where properties are more affordable in certain parts, demand is relatively good (less vacancy), healthy cash flow, and tenant laws are more favorable to the owner side in case your tenant stops paying their fair share. 

I’m struggling to see how I can afford to get into a second house with my current DTI.

I only sold a few amount of properties but the values of the homes have increased.The government is making less affordable homes(Impacts supply)A lot of the points you suggested such as selling costs and having to rehab the property before sale apply to both cheap homes and expensive homes

Should I assume the in-place IHDA loan at acquisition or close with a conventional loan and try to get IHDA loans/grants/credits later if/when I decide to keep affordable?  

Start small and consider areas like Georgetown, San Marcos, or San Antonio for more affordable opportunities and long-term success.

@Cesar Jaramillo if you can afford it, live where you are the happiest.Good investing...

They also tend to stick with locals to create more affordable housing by locals for locals.

We got hit with some surprise costs that I can’t afford.
