I think that you would be put in a vulnerable position being just another solider renting out his property as he is deployed or transferred overseas.  

I handed out cards and received a lot of great insight from people who respected me for coming in and showing vulnerability. 

You mentioned a bunch of "what if" scenarios, but it's what you DIDN'T plan for that the insurance will help you with.Properties....especially when vacant.... can be very vulnerable to anything from theft to arson and everything in between. 

Landlords have the power and tenants are far more vulnerable, yet the latter thinks it should beg for housing.

Nice post there was a thread on Do hard money actually been many of them. they will actually fund 100% but you need to pay them a 3k fee or there about up front with no guarantee of funding then its something like 650 per submission according to those who have tried it and posted on BP .. so many of the folks posting on the thread about the company paid the up front money 2 to 3k the 650 submission fees a few times and the deals were never good enough in the eyes of the funding company.. so there you go out 3 to 4k and time and effort.. some on top of it some  were naïve enough to put down non refundable EM with a wholesaler and lost that as well.its quite a model... little to no down side risk and prey on newbies who are the most vulnerable and want to get into the game and I suspect most of them even pull the 2 to 3k fee off of credit cards.So what do you have1. newbie  ( does not really know what a deal is yet2. limited capital but burning desire so they risk the 2 to 3k3. only a screaming deal gets funded as you stated.. newbies generally don't fall off the truck into screaming deals.then you have on the internet  what I call pump and dump due diligence scammers  these are flat out crooks of the Nigerian prince scam mode.. promise you 3% loan 100%  two e mails and your approved.. broken English just need 500.00 to move forward...

Would I be legally vulnerable since it was Tenant A who actually made all of the payments on behalf of Tenants B and C?

Unless have built in 30% downside risk into your cash flow statements (income and balance don’t mean much) I believe that your property is vulnerable.

And the taxes you have to pay reduces the effectiveness of your withdrawals.2) You will be putting all your eggs in one basket, it will leave you vulnerable if something goes bad with your real estate investment.3) Based on your current income of 5K per month, I assume that if you live frugally for couple of years then you can save 40K or so.

Sure, but that's where similarities end.Literally just had a storage unit rent payment (ACH) reversed 20 days after I received, not on Cozy but on a different platform.Don't really care enough to discuss any further, was just stating that in Cozy's defense, their platform isn't the only one that is vulnerable.

But if this might be the debt-straw that makes your portfolio-camels-back vulnerable to breaking it's a tougher choice.
