I have made many changes to the exterior (new roof, paint and landscape).

I’m pretty familiar with cost efficient ways to remodel the interior but I am not well versed in exterior options.

A couple months ago I was looking at a triplex that came up for sale in a close suburb,   long story short despite suffering from long term poor management, needing substantial exterior repairs, and having damage and 2 vacant and gutted units left over from tenants-from-hell it ended up selling to somebody else for 30% over asking,  needing another 20% of the asking price (at least) in repairs.

First of all when we opened up a lot of walls we noticed there was a lot of water damage and we had to replace a lot of rotten wood along with all new insulation on exterior walls and a lot more sheet rock then we anticipated.

He then hired a foundation company that put in 9 exterior piers to level the house and it came with a lifetime transferable warranty.

I’ve seen window units permanently installed through exterior walls in other MHs.

You could save some here if you hire out any structural walls (exterior or interior load bearing) and do all the interior non-bearing walls yourself. 2- Drywall sucks....but you can save a TON doing it yourself.

It's just common sense, but sometimes you just need to read it.http://www.littlethingsmatter.com/blog/2010/02/17/...https://sajigroup.com/law-of-magnetism/I'll leave you with these words from John Maxwell (I believe): What determines if you attract people with your desired qualities is not what you want, it is who you are, that is how the Law of Magnetism works.
