Quote from @Kellie Powell: Sometimes hiring a contractor to do a project here and there will save you time...which costs you money.This is where most non-Contractors go wrong.

I've found that CPAs that focus on a niche area such as real estate rather than offering general services to everyone are typically much more knowledgeable about real estate tax incentives.

I was thinking about adding this- that the renter should be responsible for paying the first $100 for any of the service calls to fix any  stuff in the house.

Try sending a registered letter terminating their services unless you hear from them within 5 days.

A Debt Service Coverage Ratio (DSCR) loan for investment properties is often considered better than a traditional mortgage for several reasons such as: it focuses on the property's income rather than your personal income.

I would just non-renew them and give them proper notice of the non-renewal.

I have tried calling the number that you provided but it was not in service.

I don't mean residential DSCR or other non-qm type loans but rather loans for office buildings, stipmalls, owner occupied SBA loans, etc...

It's a budget friendly option to some of the other services, and they have engineers on staff + audit defense, but the more expensive cost seg companies ($1500-2500) will actually do walkthroughs of your property via Facetime to more granularly estimate components of your structure. 

More than 50% test.You must have spent more than 50% of your working time during the tax year performing personal services for a real property trade or business.
