That said, I do this with a a few investors on rentals since I'm a Realtor and Property Manager where I am boots on the ground for purchase, rehab and lease-up, however we had a strong professional experience/life together before partnering.Lending will also be a consideration as most lenders are hesitant to lend to non-citizens given the foreclosure challenges it can pose.

Quote from @Jerry Zigounakis: Wondering what everyone's experience is starting an LLC or sCorp to purchase your investment properties under?

I am not sure if I would make the same decision today.However, if you think you can purchase real estate and have a SIGNIFICANT delta as an investment, I would not cash out the 401k now to buy real estate. 

@Jay Fayz for SFR (1-4 family) Classifications are mostly opinion-based.Not aware of anyone tracking eviction rates, except Evictions Lab nonprofit that doesn't like landlords.Here's some info that might helpt:---------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Hi Kyle.With the right purchase, any market is a good market.

You could get everything in writing but you'd have to evict if purchase didn't go through.

A good sign of an agent is how much business they are doing on the purchase and sale side.

My suggestion if your goal is to free up some equity to use for another purchase - start small with the single family home with a cash out refinance.

This is a story from my past that provides a perfect example as to why investing in tax liens at auction is so dangerous for any but the most experienced and knowledgable investors20 years ago I purchased a SFR as a long term rental investment that sat on a double lot.
