There is a massive dehumidifier that effectively keeps the dampest part of the home (the 1926 era basement) at 50% humidity or less.

It will make those properties harder to sell and will depress the selling prices.If all you own are SFH that you plan on selling to owner occupants, you may see little or no effect. 

I don't ask for this, it's just sort of a psychological effect of them having 'senior' status. 

@Leigh Ann SmithIf you are going to have them on a trailer, based on the costs, I think just buying some camping trailers would be more cost effective. 

We have very little turnover.This niche is not for everyone and it does take some extra attention from time to time, but if you establish clear and honest communication at the start, show respect for others, establish efficient and effective systems, and attend to issues as they arise, you can do well.

Does anyone have any suggestions/advice/guidance on how to utilize these leads effectively?

It will take me  a few hours and a bunch of edits to tell my story, so here is a short Quick reply, i started real estate straight out of high school,in the toughest parts of south central Los Angeles no car no money i will say this if you learn how to communicate and talk to sellers in a humble sincere effective manner you will be surprised what a seller will be willing to do to sell their home to you, in my experience it is not who offers the most money it is who makes the seller feel more comfortable, im refereeing to FSBO's, reo's etc was not popular back then but foreclosures were on fire, i was pretty good at talking and adapting to homeowners in distressed i'm very big on what i call the "like factor" so i was able to arrange terms that some of you would not believe me if i wrote it in a post, my point is yes you can buy with zero money (if you have the knowledge and know how) it is several ways to get a deal done when you have no money.

A big area that I am striving to improve upon in managing a business is being more consistent in order to scale my business effectively.

That is a pretty effective marketing program.

I was hoping to receive advice on effective ways to reach out to buyers for a vacation property, where a potential buyer may not be local.
