They're always quicker, are unsecured so no need to pay title fees, no collateral so no appraisal costs, and can fund in 5-10 business days.

Then its just a simple promissory note with the property being the collateral.  

I'm not real sure how people are able to get loans "over-leveraged" , even if I cross collateralize, the equity has to be available in some property or the bank won't do it?

The lender may allow a seller note in 2nd position, but most likely they will want additional collateral if you are leveraging 100%.

You either need cash or collateral to put up - which do you have?

Your using your money as collateral for a loan from the bank. 

If you have (6) cash flowing properties you can always cross collateralize the properties and not use hard money. 

The initial thought was to begin cashing out but we'd be faced with the tax implications - wondering if anyone has any experience with a line of credit type product backed with a portfolio as collateral.

He stated you could use a retirement account as collateral for an unsecured loan.

Mobile homes use different loan companies than regular real estate, because you do not own the land, and because it is "mobile", there is no collateral for the lender to foreclose on if needed.Some reasons why you do not see many mobile home vacation rentals in communities in Rehoboth are:- Community does not allow it - period- More Difficult to get a lender (not considered real estate)- Expect Community Lot Rent to go up every year 5-10%- Add your electric/gas, lawn maintenance (which is mandatory in a community), pool fee, insurance, etc.- If you cannot walk to the beach, must have much much lower rates to compete with others / renter pool reduced considerably- High Vacation Season is now only about 6 weeks, where you can get top dollar rent / then another 7 weeks for shoulder season rent / and the rest of the year is lucky to get enough to break even - or get a long term renter for the off-season, where now you become a landlord vs. a vacation rental owner at a low rate, where hard to find a good renter that won't trash the place - & then landlord/tenant laws apply - may not be able to evict if needed in time for high-season guests (now what)- More upkeep and maintenance needed on a mobile home - they are not built as well/sturdy etc. as a stick built home on a foundation- There is a stigma attached to "mobile homes"- The numbers just do not make it as good an investment, when you add devaluation into the calculations- Resale is like a car, devalues over timeHOWEVER- If you find a community that will allow short term vacation renters, and you have all cash, you can probably find a good deal on an older used home where they numbers make more sense.
