Code for your area may include plumbing, electrical, bedroom windows (proper height, width and clearance for egress), some areas require sheet rock around the heater and hot water heater. 

This process is quite specific and must be adhered to with strict guidelines, including timelines and the nature of the property being purchased.Another method is the lazy 1031 exchange which is banking passive losses on your 8582 FORM from depreciation on other parts of your grouped portfolio such as several other real estate syndications.

Many investors have full time W2 jobs, myself included.

Other considerations things to look at include; are any utilities common (like paying for a boiler for all 4 units instead of individual furnaces), how does access/common areas work, do the tenants all have access to laundry, are there any common area utilities (light common area lights, electric or gas for laundry) that would stay in the owner name.  

Be sure your marketing and your application include whether you have a pets/no pets policy; assistance animal policy; ALL adults must complete application and will be named on the Rental Agreement; utility responsibilities; SD requirement; when and how various funds are due (app fee, SD, initial rent, etc).

@Jordan Hanks - Some companies including Evolve Vacation Rentals charge 10% for booking and marketing, with extra fees for cleaning, re-stocking, etc.

I do not know anything about Anderson Business Advisors, and have no comment or feedback on them whatsoever.I have set up multiple LLCs for various business ventures through top notch attorneys - never paid more than $900 for any of them, and that includes all state taxes and filing fees.  

If the buyers buy the right property, the cash flow should be more than enough to cover all the costs, including that of the financing.

My view is there is risk in unpermitted work including getting caught and having to come compliant and/or not being able to rebuild if something happens.  

If they deny the incident entirely, then I would get a copy of the police report and use that as justification to send that lease violation notice and include a copy of the report so that they know they can't get away with lying to you.
