If they have never done a MHP loan, don't waste your time. 

The expense is more up-front but is far more cost-effective in the long run.Regarding your specific question, unless they have an agreement with you there is no expressed or implied contractual obligation for you to hold the rent. 

From the agent's perspective, though, I understand the risk and unwillingness to "waste" time if you aren't sure a buyer is truly serious. 

I am confident that my wife and I can retire on a reasonable income within 3-4 years through investing in real estate since our 9-5 jobs provide an exceptional amount of capital as long as we don't waste it.

You can save time though by getting a feel of where the seller is at before wasting time on a walkthrough. 

The waste line will be more of a challenge, but certainly doable. 

This, in turn, makes each investment a little safer because it reduces the effect that experiencing a loss will have on your wallet. 

How do I make a system that uses the drivers effectively?

However, it does have the effect of reducing the passive loss balances you will be rolling forward by 10K. 

Finally at the end of 2020 my wife told me; "you are just wasting money on this".
