The game has changed since COVID made remote workers a main stream phenomenon.

I was able to get my offer accepted 3 houses, 2 in the colony(75056) and 1 in Carrollton (75006).

Unless you think rates will fall to the point where someone would accept even less cash flow later? 

Due diligence and contingency clauses are your opportunity to back out due to new discoveries that you didn't know about before making/getting an offer accepted (i.e. inspection findings or appraisal issues).

I’ve made, what I thought to be, competitive offers on 4 other places which were not accepted.

in those days no seasoning at all.. and of course the buyers who bought into our program were in the home completely renovated at 65% ARV.. the 75% ARV loan dropped and they would get some cash back 5 to 10k per house we usually had them buy 4 at once.. and cash flow that was common and acceptable in those days was 100 a month positive.So they had to put 1k down on my loan  then they got back cash at close and had 100 a month positive. 

It’s very realistic to find a lender that will accept 80-100% rental income using their rental worksheet.

I recently accepted job that's 100% remote.

., make sure you can close if your offer is accepted. 

There are some online software that you can use as well, including some that accept rent payments.
