How differently are you analyzing deals when going all cash? 

Thanks Matt If it is legal, analyze your area to estimate the income to see if it makes sense for you.  

Once you analyze and view multiple properties in an area, you start to see what is typical and what you are looking for.

Then they help analyze the purchase deal when it arrives from the solar companies.

As for underwriting, when analyzing use the numbers you think it should be to see if it would makes sense. 

BP has various tools to help you analyze your deals (rentals, flips, wholesale, etc). : https://www.biggerpockets.com/investment-calculators7.

Not because you've analyzed her situation or her options, but because you were saying "extra principal only payments will yield similar results." 

Texas is indeed a competitive market, but with your background in IT and experience with stocks, you’re already well-equipped to analyze deals and make informed decisions.If you're open to exploring markets outside of Texas, I’d recommend looking into areas like Indianapolis.

The first thing you'll want to do is run the numbers with your lender(if you need a local referral let me know) to see what price points you'll be able to look at and then you can also start seeing what mortgage payments are going to look for the two different property types this will allow you to get down to analyzing deals.

Trying to analyze as many as I can so that hopefully I'll recognize a good deal when one comes.
