So I am looking at buying an older house and we noticed the foundation on the back corner of the house has an issue. It's about a 4 foot section of the corner that seemed to have broke off and tilded down. They owners...

It's a great industry that I hope to do full time and meet with other smarter park owners on a regular basis but it can also hurt you if your not sure what angle to tilt your head to really see the beast

I won't be investing in the riskiest/most supportable asset subclasses such as hotels, and tilt my portfolio the ones that have historically been more stable such as multifamily and single-family housing.

Often times if there is an issue with the retaining wall, it will be apparent (cracks, tilting, etc), same with drainage (evidence of past erosion, water pooling) and foundation (cracks, displacement, etc.).  

However that's because you're adding in your own personal housing expense into the mix, which is what tilts the overall numbers negative.

My research has also revealed that most of these waterproofing solutions dont work for various reasons(no proper tilt in drain system so water sits stagnant and becomes smelly, no drainage at all...b/c they simply drain to under the foundation, etc).Now I know what to look for in a company, but I have a friend who builds houses and I might try to get him to help me do this myself...and maybe...just maybe...I could save $5000?

If you have really low rents your repair costs could be a higher percentage and then the rule might tilt over 50% because a roof might cost 10k on a unit bringing in $750 a month as one that brings in a $1,000.

The natural supply and demand will tilt in favor of multi's.Overall, you will need to put 25% down on sales price of 280-300k.

I see bowing/tilting in the wall on your 2nd pic.
