(yes, they are lien-able, and depending on the boro sometimes they are billed monthly or quarterly, sometimes one utility bills for all 3 services or different utilities bill for 1 or 2 of them or each of them) 

Hey guys I hope everyone here on BP is doing great and ready to crush this 4th quarter! 

My main question is about the basement, about a quarter of it had concrete, but the rest was gravel.

Here are some other things that could go wrong which may cause failures:Unknown necessary repairs (i.e. sewer lines, roof, etc)Not having cash reserves to cover vacancies / major repairsUptick of crime / vandalism in neighborhoodVandalism of propertyInfestations (pests, other)Bad tenants / No tenants / tenant family issue impacting stay (i.e. death, divorce)Rezoning of school districts / Loss of accreditation of school district Insufficient Property Management (not addressing tenants concerns, no notification of repairs timely - causing further damage, etc)Not following market pricing on rental / raising rent to frequently or too much at onceLegal issues (i.e. tenants sue for injuries on property, taxation, etc) I think you get the idea.

This might include things like intent at the time of purchase, time held, whether a property was marketed for sale, frequency of such transactions, whether you are personally flipping houses separate from the plan, etc.If your IRA is flipping properties on a regular basis, then you will surely want to speak with your licensed tax advisor to be sure you understand the ramifications of UBIT taxation, and whether this tax on the gains from flipping will still leave your IRA with better returns than other options, or if you might need to look at different strategies for the IRA such as long term rentals or hard money lending.

Do you guys update yours with the market value of your real estate each month, quarter, year etc.?

Hi Daniel, Absolutely, I frequent Boston's back bay several times each quarter for corporate meetings.

And I have phases were some bank and some don't buy a quarter later and the tides change and lists perform differently.

They typically meet once a month or a quarter and it's a great way to find a mentor.

The water is billed quarterly, and I am afraid that if there is a leak somewhere I won't know until I receive an enormous water bill.
