Efficient negotiations secured the property for $200,000 on favorable terms.

From what I see Rently seems the most secure due to the credit card auth.

You will likely get two different answers to your question, and it ultimately stems from your usage of the word "foreclosure".The word has technical definitions, and as JD pointed out, in a sub2 deal you don't have a security instrument that authorizes you to foreclose on the property. 

Additionally, maintaining a strong credit score and keeping your debt-to-income ratio in check will make it easier to secure financing for future properties.

You will also need this info for contact information, etc.Request in your offer a letter signed by both the seller and tenant agreeing on the current value of the security deposit.

@Nilusha Jayasinghe I always collect a potential residents social security number, DOB and license.

You’ll pay a dear price for privacy and security but peace of mind may be more valuable to you.

Is an interest in a DST (Delaware Statutory Trust) considered real estate ownership or a security in Florida? 

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.

Most of my purchases, and clients I work with, are leveraged so we are looking for as much consistency and security as possible so that puts us in more owner occupied type areas.
