Unless specifically allowed or required by Section 8, this is often illegal both for the tenant and the landlord and you will often be required to sign a document to that effect. 

You will need to invest in a syndication that has a TIC(tenants in common) structure set up.Since it is more work for the sponsor, they will normally require you to put up more funds to make up for the extra work.

Also, require your tenants to hold renter's insurance.

I’m thinking a less expensive granite vs. quartz in kitchen, maybe not spending a lot on the showers/ glass and trying to finding cheaper cabinets for everything but the kitchen. 

It depends on your requirements. 

A successful partnership requires the following three - Money, Time, Experience.At the moment, it doesn't appear that you have Time or the experience.You should partner with someone who can fill in the voids, so you want somene who has the time and the experience, given that you have the money.

They will cost $100k to get going and having to have an audit done to comply with sec requirements let me tell you is a blast (insert sarcasm).

Most lenders require you to have completed 2-3 builds under an LLC, where you were either a guarantor or had at least 25% ownership.

This will require purchasing multiple properties.

Both still require registration of the property, etc.Hope that helps!
