My goal is to grow this business by expanding my investor network and seeking properties that will allow for additional scalability.

Especially for the cost.

This is a business.

Quote from @Chris Magistrado:The point he's making is that the agent must take responsibility for building and maintaining their business, and the Broker won't play much of a role.

We have built a very similar business here in Austin.

Our business model is built around working with investors to find them great returns and I would enjoy a conversation around what you are trying to do.

Whether the seller was open to a buyer commission or not, I wouldn't put an additional cost into any personal purchase.  

From there we identify properties that could have some potential and if you are interesting in diving deeper, 1) we do a thorough video walkthrough to give you a realistic look of the property, 2) we give a ballpark estimate of rehab costs (we do 40 a year with our GCs o we will get pretty close), 3) we talk through market rent with our property management team, ARV, and potential highest and best use.Ideally you find great investor agents who know their market really well and have a network of resources to provide you with enough confidence to take reasonable action. 

You can check with the Better Business Bureau (BBB), your state’s department of business oversight, or your local real estate community.5.

Also, what are some other low cost amenities that I can add to my STR that will yield a higher ROI?
