I bought a 3 bed/2.5 bath house in Jonesboro, GA with a finished walk out basement on 2.5 acres, 2 car garage, and large decks for $22,500 in 2010 that needed a new refrigerator and touch up paint.  

Ipe is the hardest decking you can use.

Lifespan Roof 30 years HVAC 15 years Siding/Exterior Paint 20 years Deck/Driveway Varies Refrigerator 15 years Stove 15 years Dishwasher 10 years

I did need to spend part of the spring redoing the deck railing, painting exterior trim, replacing some deck boards etc.

They haven't been inside but they're already saying all the decks need replaced and probably the HVAC as well.

Most long term parks require tenants to fully skirt their RV (so look for skirted units) and most tenants who really are staying long term will build an addition, deck or patio, install a storage shed, create a garden, and show other evidence that they have made this their permanent home.

Replace warped boards on deck and house= $3502.

(You can use purchase price plus cap ex (your $$ into home improvements like new deck) or fair market value (your home's expected sale price), whichever is lower.

Not sure if you have any template pitch deck that you work with but anything that you can share would be great.

All new windows (some larger, some removed), new floors and paint, removing a few walls that aren't structural, two net baths, making a basement into a room, closing off another room by extending the floor a little and adding a very small piece of wall, adding a swamp cooler, new water heater, vapor barrier, replacing kitchen cabinets, adding tub in one of the bathrooms, moving toilet bowls a little, adding a larger deck, etc etc
