Deal on line. 

Thereafter it should be safe to  accept a personal check.- Phone numbers (include cell, work, message, nearby relative)- emails (personal and work)This is how I've been doing it as a manager for my own properties and for my clients. 

If it is not feasible to visit the office and you have to make an online purchase, always verify there is a good return policy:) 

You can seller finance to another investor as a commercial loan, but you're speaking about consumer financing.As I said, read here on BP, there are a few, not many, who know seller financing as it is required to be done today so be careful about what you read on line.

Is it a smart and safe option for me?

I found several online but I don't know how to compare them.

In turn I will be able to invest my money in a safe way and provide both company ventures benefits at the same time.

You are safe.

My suggestion is to be safe and call the Property Appraiser’s office to be sure.Hope this helps.
