First the disclaimer: one turnkey property (or DIY rental) will not a sufficient income make.

Hey Travis,You can buy another investment property right away using conventional financing assuming you have sufficient down payment, credit, and down payment/cash reserves to qualify for another property.You can use your rental income to help offset your monthly PITI.

The issue comes when you're LLC isn't established enough to have a decent and sufficient track record yet.   

I have excellent credit and sufficient funds. 

I see my six isn't sufficient. 

You Can Catherine but you will come up invariably upon the Self Sufficiency Rule (or SS Rule).

Generally, the normal documentation of the transaction is sufficient proof of the “per se” exemption.

If seller is not sufficiently motivated, cash is irrelevant.

The reason I mention the 'high income' in particular is simply because right now, I seem to be a pretty solid bet for most lenders whereas I'm not sure if my net-worth in stock will be sufficient to get a good mortgage rate since my 'income-to-debt' ratio will be dramatically different.I don't intend to try taking on a bad deal in the short-term just because of the whole mortgage-lendability-risk issue, but I'm trying to figure out how much of an issue it really even is in the first place and how much I should take it into consideration.If I don't have an active income, presumably (and please, correct me if I'm wrong here) I'd still have some potential to get mortgages, but they'd be at a higher rate (e.g. maybe a couple percentage points higher)?

Your chances of surviving such an event probably depends on how leveraged you are and whether you have sufficient reserves to make it through.
