@Silvana Elejalde I will give you some tips. However, realize that I am not generally a Florida buyer, so I am not that familiar with the intricacies of Florida recording/court systems, etc. However, here are some tips that may be helpful, using knowledge I've gained from being in the property records in multiple states with very different systems.
Do you recommend I physically spend time at courthouse doing searches instead?
Realize that in any judicial foreclosure situation, the property records and the court records are going to contain very different information. The property records will be useful for establishing lien priority, based on the recorded date of each lien (and any subrogation agreements). The court records will detail service of process on each defendant, whether they have appeared, whether there have been any agreements re: subrogation, etc. It is irrelevant if the lien being foreclosed has priority if a junior lienholder was not properly named in the foreclosure lawsuit; that junior lien will survive if the junior lienor was not named and properly served. Therefore, you must search both the property and court records to get a full picture of whether to buy at auction. Sometimes, courts provide online access to their docket filings, sometimes for a fee. Obviously, find out if this is an option, so you don't have to spend lots of time at the courthouse. Also, it doesn't hurt to get familiar with the rules for service of process; improper service of process can blow up a perfectly good foreclosure auction and lose you a lot of money.
Double check using Property Radar?
As I mentioned in an earlier post, I think Property Radar is best for bird dogging, but it certainly doesn't hurt to sanity check using Property Radar as well. If Property Radar shows a lien your own research does not, you must reconcile the discrepancy before moving forward. Never hurts to source your data in multiple places and then sanity check against one another.
Case 1
Generally, once a Lis Pendens has been filed in the property records, that is notice to all subsequent encumbrancers and transferees that the foreclosure is taking place, and should bind any owners who took title after the lis pendens is filed. It wouldn't surprise me if transferring the property automatically delays the foreclosure while the foreclosing entity determines what is going on. However, this title transfer tactic might also be an attempt to do a work out with some kind of third party funder, etc. Generally, I would say that this shouldn't be of concern, but might indicate that the foreclosure sale won't take place because another investor is trying to take title prior to doing a workout with the lender and borrower.
Case 2
Because of the principle I articulated above (liens of unnamed parties aren't wiped off in foreclosure), foreclosing entities will often name any parties that might have an interest in the property, regardless of whether they have filed a lien against the property. These entities probably came up on a credit report, or possibly from a bankruptcy filing. You should do your best to identify the source of these named parties, to verify that there isn't some outstanding lien or statutory superlien (these are generally sewer/hoa/water district, etc, but it can vary by state). However, sometimes foreclosing entities have better data than you will have access to, so some level of uncertainty may remain. Remember, if you ever feel uncomfortable about what the data is telling you, it's a lot cheaper to walk away than go in half assed to a foreclosure auction where your cash is on the line. The question of whether the creditors have the ability to claim money from the debtor is separate from the question of whether they have a lien that is superior to the one you are foreclosing. The debt owed by the homeowner is not your problem; liens superior to the one foreclosing at auction are your problem. Always best to identify the source of all named lienors so you can determine which is which.
Case 3
MERS is an entirely separate bucket of worms. In short, Mortgage Electronic Registration Systems is an electronic database that tracks the transfer of note interests between lenders, as a way of avoiding property recording fees. MERS records itself as the "beneficiary" of the deed of trust, and then tracks the transfer of the note internally among various investors. This is a highly detailed topic involving the Uniform Commercial Code and state law. This is an excellent primer on the topic, if you care:

The break in the chain of title that you identify, with Bank of America seeming to appear out of nowhere, is an aspect of MERS that has come under severe criticism from courts and attorneys. MERS serves to obfuscate the ownership of the note and deed of trust, and MERS has been inconsistent in its description of the legal theory surrounding its business, depending on the context (but I digress). When a note goes unpaid and the mortgage/deed of trust needs to be foreclosed, MERS will assign the deed of trust to a bank, that then forecloses on the property. In Florida in particular, foreclosures have been unwound because the bank initiating the foreclosure can't prove that it owned the note when the foreclosure was filed. This might be worth learning about, since this is a common problem with MERS in the chain of title in Florida.
Regarding the second mortgage, because the foreclosing entity owns both, I don't think they could argue that the second survives, as long as they are foreclosing the first. However, make sure that the foreclosure court documents clearly demonstrate that they are foreclosing their first lien. You don't want to buy the foreclosure of a second, thinking it was the first. As I mentioned above, you have to read the court documents. You cannot assume anything.
Should I do a title search with a title company on the ones I'm interested?
Title searches never hurt. Could be the cheapest $50 you ever spent, especially if you're not that confident about your ability to properly search the property records.
