We both are drawn to either single family long term rentals, or STR’s in the right locations.Right now we have $20k cash available for immediate investment, with the ability to increase that to $60-70k in the next 3 years through savings and bonuses at our day jobs.

sounds like a good deal. a couple things of note to hopefully help: SFR w/ ADU is fantastic, you don't want this to be a triplex on paper. do your DD here, and make sure those ADU's are properly permitted as such. if you intend to live in the property you will have to qualify w/ some type of ATR rules (income/ Ability to Repay).

Some of the clients that I work with like the ability to  have an easier time qualifying for business lines of credit, business cards, or other forms of credit that is not specifically a mortgage or real estate related.

The people who will be hurt by this are the people who are wholesaling from other states and the people who don't have the ability to fund a double close. 

@Amit Shukla No one has mentioned the claims paying ability if the insurance company.

In a year if you finally got an eviction you lost the ability for that $100k to generate revenue as a squatter house is not going to be appreciating based on the condition they will leave it for you.

Leverage is always cheaper than having a partner.Paying cash for me is important when:  Paying cash gives the seller confidence in my ability as a buyer. 

Could you share more about your current abilities, and what you'd most like to learn?

That could overpower your pump's ability. 4.

Following and reading through this thread as I am in a similar position to the original poster.I have evaluated some of the programs out there such as Brad Sumrock, Gino, Rod K, and others ..For me, the value has to come from the ability to have access to people who can help provide deal flow and others who are in a similar position as I am that would be willing to partner with complimentary skillsets.
