Some other banks will tell you 40% to manage your expectations but if you have a good credit and a the deal makes sense, the down payment shouldn't be above 30%.As to the managing of properties, if you can self-manage out-of-state in the US, there are no reasons as to why you couldn't do it internationally too and some investors do.

But, we now live across the country and managing from this far just doesn't make sense for us anymore so we are ready to sell.

How does that make sense? 

If I sense any of that nonsense, I tell them I'm out. 

Makes more sense to me to build equity through development and income as opposed to "comps" for SFH and small MFH. 

I have several and will buy more as they make sense.

@Robert Guarino, That makes perfect sense. 

Our goal is to always buy, but we are only willing to purchase deals that make sense and work for our investors. 

If you have passive losses or a step up in basis, a 1031 exchange or reverse may not make sense. 

I’ve used seller financing as both a buyer and a seller and it can make a lot of sense in certain circumstances (for example I used it as a buyer when I reached the maximum number of conventional loans I could get, and I’ve used it as a seller to both increase my net proceeds (due to collecting interest as “the bank” in addition to the sales proceeds) and to lessen my capital gains tax hit by spreading it out over a few years).
