Let's break it down into two pieces, the LLC and the partnershipThe LLCYour current operating agreement should lay out ownership structures and contribution.  

As a GC I can advise try to retain control of your finishing material orders (anything where you need to make a choice ((tile, flooring, lites, faucets, tubs)) vs. construction materials (2x4s, mortar, shingles)) because we get those discounts on the finishing items and we keep them!

I just talked to customer service and they said Landing has discontinued their listings and is terminating services and laying off staff. 

Tell them your plan and they should be able to lay it all out for you in one phone call.It's way better to have professionals who you can turn to, rather than try to learn everything yourself.

Lay low and stay out of the crossfire.

Just lay out the rules on pet size, breed, and how many pets are allowed.

Mulch or Ground Cover: For the back, you could lay mulch or gravel temporarily.

I too have a holding company; this might be a silly question but is this something I need to relay to tile, or they do automatically?

Hiring a bookkeeper to watch the income/expenses is like hiring a gardener to tell you how many roof shingles are laying on the ground after a wind storm instead of hiring a roofer to repair the roof.I recommend that you look for a quality property manager who can maintain the properties and help with the bookkeeping.Start by going to www.narpm.org to search their directory of managers.

The key is to simply lay out your options and determine which one offers the highest return while staying within your acceptable level of risk:Rent and save for a 20% down payment on an investment propertyBuy a primary residence without house hackingBuy a house hackOther: Is there a better use of your money?
