Is this tied into house and potentially creating larger foundation issues?  

I currently live in Silicon Valley but house prices aren't feasible for me here.

By quickly assessing the market and taking advantage of the property's high demand, Partner Driven added value through a well-timed sale without requiring extensive renovations.

Initially, we planned on house-hacking a multifamily property.

If I kicked him out earlier I had to do a renovation right then , I collected 4 more years of rent , the renovation was paid for with 1 years rent and the deposit .

So I started $60k in renovations to boost rents. 

If I could do this all over again, I would probably go for a smaller house.

We scrape rental data, underwrite the entire market all at once, assign a renovation level, and rank them on their cash flow potential.

You want to break down your preference in regard to sale price, down payment, program, (SFR/MFH), seasoning is important, and the two R's you want to pay most attention to is the Renovate and Refinance.Most investors make the mistake on the renovate or refinance and sometimes both.You also have to figure out if your buying as a Primary or investment because if you buy as a primary you always refinance before you rent. 

For example, one house had taxes of about $3,000 per month and they are now right over $6000.
