I guess it's just too many factors to consider and it easy to get overwhelmed and cannot get accurate info and estimation when I conduct analysis (ex. property tax rate, insurance, maintenance fee, rent, repair, closing cost, etc.) 

Amortize your major repairs (roof, hvac, built in appliances) and add an estimate for small maintenance.This feels not terrible to me.

If your estimated rent from a property pays off the Mortgage + Maintenance + Property Tax + Insurance.

As an experiment I invested $30k each in the 10 REITs which had (according to average estimate of NAV) the largest discounts from net asset value as per market price).

But then he said they had to have a contractor’s estimate on the Indiana house and the money would be doled out as things were completed, so could not be used in Spokane.

Don't get me wrong I'm happy to help get you some estimates if that's useful hahah but still not something I'd recommend. 

You are best off to raise the rent and give the tenant the option to stay.Also, I hear a lot on here that "rents should be", "the potential rents are"... make sure that you do your due diligence when calculating potential rents because most new owner OVER estimate them.

Research comps in the Milwaukee area or connect with a local appraiser to estimate your property’s potential value.Depending on the rental income, you might explore DSCR loans for your refinance, as they rely on property performance more than personal income.

Managing it has been exhausting, especially with the tenant issues and LA’s landlord policies.Here are some details about the property:Purchased for $650k, with about $90k spent on renovations.Current Redfin estimate: $1.1M.Mortgage interest rate: 3%.Would selling it “as-is” during the eviction process make sense financially?

I only replace things that would make the appraised value come in at lower than my estimated value or that are likely going to stop working or cause an issue within the next 3-5 years.
