Also are you doing credit checks through them?

The most important rule is to have the cash flow of the new property be able to pay all its expenses, mortgage, AND the line of credit back.

At least ones that will walk the property with you and give you an fair estimate. 

With the exception of building a trailer on the property (these are hard to finance), this sounds like a good plan AND if you are using it for your business AND your business pays more than 50% of the rent (if you have more than 1 tenant), then this is a more financeable property in the eyes of banks and credit unions as it would be consider a commercial "owner-occupied" property. 

It has a fairly solid workflow. 

Thanks for the feedback; some quick stats: 9 doors across 4 states, about 50% LTV ratio with a Net Income of about 17% and cash on cash of about 3%.....in fairness those numbers include some overall business expenses not tied directly to one specific property.

Flat Fee MLS Brokers for sellers have been around for a long time, but Flat Fee Broker/Agents for buyers with a cash credit/rebate of the buyer agent commission are quite new and just starting to get some market share.

It's not fair for his future landlords not to know about this terrible tenant.

And even if they do, they have to be fairly motivated to be willing to do so (even if you've built rapport and all that good stuff).If they are motivated, usually that means the property needs work and they almost certainly won't lend over and above what you buy the property for.

I would say credit monitoring
