DOM can be minimized by a number of different factors including the quality of marketing, rent price, availability to show. 

You can go to Redfin or Zillow and see the level of finish houses with short DOM have in the area, can you at least match that quality?

Keeping our overhead low and estimated revenue high.

Also, SAAS platforms are supposed to include support and service (that's the last S), but the quality varies greatly from company to company. 

there is tremendous demand for inventory right now, and as you have already found high prices and high rates have hurt cash flow. 

I assume it’s not high enough that you or any family members want to take on the job?

I am not familiar with how HELOCs work but they declined me saying my DTI is too high.  

Buyers don’t care if you shelled out more on the rehab, if you’re priced too high, you’ll end up sitting on the market way longer than you want, driving up holding costs.Lastly if your buying on market, REO or Corporate sellers are dominating and not as willing to negotiate as owners would.

@Serge Hounkponou Recommend you first figure out the property Class you want to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Taxes are very high and everything is super slow and bureaucratic.
