Since I recently had some expensive credit card and medical bills, my cash reserves are extremely limited, but I would very much like to make this deal happen.I own two other rental properties and both currently have tenants.

Can all rentals be used by one credit card and one separate checking account then have another of each for personal stuff?

Next step is to dispute the transaction through the credit card company.

Will need good/great credit scores and probably 25% plus down.  

However, since both units are rented this would be classified as an investment property in which case your rate will probably be 4.00% to 4.250% on a 30yr fixed depending on FICO credit score.The maximum loan to value for a cash-out transaction (investment property, duplex) is 70%.Based on the information you've provided it doesn't appear the value is high enough for the property to be eligible for a cash-out transaction but you can still remove PMI.If you want to send me a PM I can run a complete analysis to see if removing the PMI will offset the slightly higher interest rate.I'm also licensed in CA so if you're looking to purchase a property I can help with that transaction as well.

I'm not a wholesaler so I'm not dealing with a high volume of leads or contacts that need to be tracked.

You are certainly on the right track.  98% of success happens in between the ears, the more and sooner you work on that aspect (the inner game) the faster you will succeed!! 

As long as u can put it on a credit card, I'd never worry about it.  

Regardless anything less than 2M +/- is left to be the domain of local banks and credit unions.  

I would advise looking at value add projects in the best markets (jobs, population growth exceeding natl averages) and sponsors (general partners) that have built a solid track record.
