Hello Solomon,A few tips I have for you would be to first; Analyze Deals Properly – Use the 1% rule (monthly rent ≥ 1% of purchase price) and calculate cap rate, cash flow, and ROI before buying. 

A 4 plex in MD at $180k...its certainly not in the DC area, and probably not even the Baltimore area at that price.

Be mindful of short-term capital gains tax, as profits from flips held for less than a year are taxed as ordinary income, and frequent flipping may result in self-employment taxes.While profits from flips do not qualify for 1031 exchanges (since flips are considered inventory, not investment properties), you can minimize your tax burden by deducting allowable expenses like renovation costs, loan interest, and holding expenses.If you're considering diversifying into rentals, explore opportunities to benefit from long-term tax advantages such as depreciation and lower long-term capital gains rates.

It never hurts to talk to agents, lenders or anyone else in the real estate realm, getting their insights and opinions never hurts.Keep analyzing different properties, you'll see (as you know) that Dallas is a large area and different prices in different areas, so see where you could potentially live and run numbers there.

So, I focused on markets where I could actually find properties within that price range.

That's actually what I did myself when I moved from Portland Oregon to Columbus Ohio (got priced out of my own market)! 

It just lacks the opportunity for commute and restaurant scene.  

Purchase price: $145,000 Cash invested: $60,000 Fully renovated 4-5 bedroom ranch on 3.3 acres.

Purchase price: $240,000 Cash invested: $39,000 Sale price: $342,000 Held property for 3 years and rented out the property for 2 years with a rental profit total of $22100 How did you finance this deal?

Unless they are offering much more cash than you can get on the flip (After lowering the price), it doesn't make sense to take the risk and sell sub-to because most of these loans are not assumable and you will take on the risk of "due on sales clause"
