@Aaron Landauhappy to help, but you said you don't want the 'standard advice'... so what specifically are you looking for?

Most cities have specifics like this for STR properties.

If those rules include interest rates at specific amounts, I will still find a way to win.

Get to know the specific neighborhood, RE is hyper-local, there is no single market in any metro area, it is comprised of many micro-markets.

Where are you getting stuck at specifically?

I have a cash buyer looking specifically in Richardson.  

You can seek out a Realtor that is experienced in foreclosures if you already have a specific property in mind as you’ll likely need to move on it quickly if it’s already listed.I would advice to find someone local to help guide you.

Many flippers I know specifically don't have their license because of the following:  no need to follow Code of Ethics, sales isn't their skill, they are making money by sourcing deals not spending time doing sales (even of their own properties since it takes time away).Happy to chat if you like. 

Note that there may be nuances depending on the specific seasoning period.

There is no DTI when it comes to these investment specific products if you’re worried about not qualifying with traditional products, talk to a investment, focus broker who can help you we out the options and leverage with a DSCR loan
