The interior paneling was usually a  3/16 inch photo finished veneer very light weight and the exterior siding was aluminum which was also very lightweight.

Usually no more than the allowed 43-45% back end ratio.

Do not try so hard and try not to expect negative things to happen.  

@Michael Newman,I use these sources:current T12 & rent roll (if available)comparable rents from broker's OM packagecomparable rents from neighboring properties (MLS, rentometer.com, umovefree.com, calling to the property)expenses provided by management companies that have similar properties under managementexpenses (ranges) from NAA survey - usually outdated but give a 10000 ft picture and helps establishing some baselines.

If its something unplanned or higher than expected, we can also use it as a negation tool.  

Of course, they do not say exactly how they did this but they usually say; "we/i with conventional loan after I used creative funding."

I am usually a great judge of character :) Thank you for the kinds words!

You may want to consider buying Non performing notes secured by multifamily, but I'd plan a heavy capex program to stabilize and be prepared to dispel any negative press as negative past tenant reviews can be detrimental to stabilization. $10k-$25k per unit is more conducive with mobile home parks, which may be something to consider also.

Usually either a short term loan with goal of owning free and clear in 4-6 years (no cash flow, let the renters earn you a free and clear house quick) or a 20 year term allowing double digit cash on cash returns.

@Patrick Philip,Well, banks are "flush with cash" these days, but no, they do not have unlimited funds.Also, when banks lend, they impose certain restrictions on the loans, the borrower, the collateral, the terms of the loan, etc. so the note can be sold in the secondary market or be insured by government-sponsored agencies like Fannie Mae, Freddie Mac, etc.Private lenders ("OPM") typically don't write loans to sell them, and typically are interested in the deal rather than the borrower's details.Using OPM down usually means putting some kind of partnership, joint venture, etc. together so the source of the down payment is less of an issue or a non-issue to  the lender(s).Dunno if that helps...
