It was a bankruptcy sale so it took a little longer, but gave us some extra needed time.

You are speaking to the wrong folks.

I suspect most of those folks will  be somewhat upside down if you take in all the interest they paid on half built homes and the cost to put those homes back into production.How are lot prices in Lehigh ??

I have seen folks that did not know basically what they were doing bid and buy seconds with no clue about the first.. 

And what are some good ways for newer folks to contribute or give back?

@Caleigh McDonough age old question.How long will it take you to save the extra funds vs how much the property may increase in price over that time?

I've reached out to lenders here on Bigger Pockets- but their rates & terms seem high (DSCR or just not good terms)- I qualify for a conventional loan, but my DTI is almost maxed so why pay an extra 2-3% DSCR when I don't have too. 

We’ve also tried talking to the neighbors directly, but they don’t acknowledge the issue or make any effort to address it, on the contrary somtimes they are extra loud in spite. 

From my understanding, mortgages are considered riskier investments than most other loans because the borrowers can repay early with little to no extra cost.

I am not in Florida, but I am one of the top contributors here as are folks like @John Underwood.
