You could discuss the issues or just respond in writing to ensure there's no emotional element.

I'm a new investor with a career in CPG (consumer packaged goods) sales and distribution.

I work with a team in Indy that provides all of the elements you requested. 

Do you have a custom seller financing package or like to use?

They were somewhat slow on process-4 weeks-but they had the best package.

But then they sent me an email trying to sell me a $3k package that includes a "starter experience education pkg, an expert experience education pkg, homework assignments" and other marketing material. 

Have a property thats avail locally. two houses and a vacant lot all being sold as one package with asking price of 220k. 

It takes us 6 to 8 hours by the time we bring in lights and post process all the photos.A critical element is the skill of the property manager.

For 1950s houses in the one package, I have a hard time believing total expenses are 35% of rents.

Call other Multifamily agents in the area and ask them for the marketing packages on the other deals they have in the area.
