I have awesome subs(foundation, framing, plumbing) I work with for the heavy lifting.

Quote from @Kar Sun: My tenant's lease is coming to a close and I am relieved she will be moving soon.She has been paying on time but has been extremely unpleasant and rude.While the money does not smell my mental sanity is more important than money in this case.She sent me a registered letter stating that she feels "unsafe because we have not done the fixes the way she wanted it".She requests to have her witness for a walkthrough.In my state a walkthrough is required but I am not about to grant it to her to bring any witnesses as that is not in my contract.If she feels unsafe she does not have t be present.I also do not treat a final walkthrough with a tenant as a final sign off.This walkthrough does not include a detailed inspection of the plumbing and the appliances that will be done after she departs.This is simply for the visible cosmetic issues and should take less than 1 hr.  

Here's what I've learned:Inspections Are Non-Negotiable: Always get a full inspection, but don’t stop there.Plumbing & Sewer: Have the plumbing and sewer systems checked specifically, as these are common problem areas in older homes.Electrical System: If the inspector flags any electrical concerns, bring in an electrician during the inspection phase for a detailed evaluation.

We had the plumbing break down and had to install new PVC plumbing Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

With foundation issues, one could have plumbing, drywall, flooring and even roof issues and alot more.

I have new plumbing and electric done in all of the units one year ago. 55k investment.

This of course depends on your starting bank roll - but if its like mine (under 100k) - Im trying to put as little as possible into it on top of initial equity and fees.this will likely chew a big hole in your ROI  (now if you are looking to improve value with a cash out refi or a great prospect comes along that needs combo new plumbing, roof, windows, foundation repair, etc - well just make sure you know what youre getting into and/or have a good contractor and finger on the pulse of the market when estimating the ARV YOURSELF - couple missed items and you risk having a bad first investment and not doing it again).    7) dont be scared be ambitious ( i should heed my own advice sometimes) 8) define numbers goals within your target areas.  

I did a lot of repairs myself but also hired a few skilled contractors for things like electrical work and plumbing.

I expect it to be moderate size rehab which to me means no significant plumbing or electrical and no walls being added or removed.  

I know people that are really good at their trade (plumbing, cleaning, electrician, etc) but they don't have financial discipline, they don't know how to market, they suck at customer service, they don't use tools to their advantage, etc.Cody Sanchez (lady in the video) buys different types of businesses and makes them profitable by applying basic business disciplines.
