I'm sure these buyers gets plenty of hollow offers like that. 

tub brand new, old tub rusting rusting and tiles not secured to wall(That was error/miss #1 we have now learned to check how well tile or shower wall is attached, if their is hollow sound problem, also was not careful in checking for rust.

There was no reinforcing that I could see, just hollow space under the slab.The current owner (an investor I believe), had already installed a new entry door.  

Hollow core doors will be full of water, too.CDC and FEMA have information on their sites for cleaning up.  

Remember you have to kiss a lot of frogs... lol. sounds like you are getting a lot of calls, direct mail is a great way to connect with folks, just the return numbers can be frustrating.

You'll probably have to talk to a lot of people and kiss a lot of frogs before you find a prince. 

Make everything in concrete or wrap it in bubble wrap like the one commercial on TV .... two things i have done with properties that i have gutted is put back 5/8" drywall on the walls, not 1/2" ( harder for them to break) and i install solid doors, no hollow core doors . it is almost impossible to make a place tenant proof, you can do little things that help to last them a little longer.

The caveat is that you'll have to kiss a few frogs before you find your happily ever after.Look for the following when searching for the right portfolio lender and be able to tell if it's their money to lend:Look for private capital lenders - Ask if they fund with their own money (a clue if they really do is ask the next question)Ask if their underwriters are in-house or outside their officesAsk what the typical underwriting turn time is (all a clue, no underwriting should take more than a week - 3 or 4 days is best)What is their typical amount of days to fund (should never be more than 30 days or it's not their money - 15-25 is ideal)Ask how they qualify income (THE BIG ONE) - No Income Qualifying is BEST (obviously) - Ask if other property income/debt is considered Bank statement income - Also Ideal to show true rental income if provable Rent roll/Schedule E - Close to a traditional deal so be careful - It usually means they'll consider all your income/debtsRental Market Survey - If this is how they do it, walk away - it won't helpYour ideal portfolio lender will require an appraisal and cash reserves (for purchase) and base the loan on the value of the property and it's condition exclusively.

Whenever I walk on cheap laminate with no padding (I assume), it sounds hollow and thus cheap, and I think better put some BC plywood down.I am mostly asking about any padding under (attached, or separate, or any) and the thickness of the laminate, expected life (wear etc.).

2005,2006,2007You NEVER go buy actual retail leasing rates for income when purchasing.The reason is the income levels they are reporting have lease rates many times that were written at the height of the economy and everything was booming.These leases are now coming up for renewal or very close.Now many of the tenants are leap frogging to better locations for the same per sq ft rate they are paying or are asking the landlord for rent reductions to stay.So even when analyzing the income and tenants pay on time as soon as you purchase they might be moving.Sellers like to dump things like this on unsuspecting retail buyers.It is fine if you base your purchase price not on what the current lease rate is but what rate at which they will stay and be able to pay and the seller will not tell you this.
