I am definitely going in legal way for sure but wanted to make sure whatever I understood from online search is correct or not.So, I should go with investment rates.Is there any recommendation to get good investment rates?

The City of Scottsdale actually has a calculator online where you can estimate the cost of your permit.

Let's be real: He claims that he can fix an apartment building and get it refinanced to cash out investors in 12 months to 18 months.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

I was just looking in our county's online court docket and see a company based in our area called something like Rent Recover handling plenty of cases, so I was going to check it out and see if maybe they can do something.

Upgrading to premium is all online.

In other words, sufficient capital for the cash purchase of a property (plus rehab) and eventually refinancing the completed project to a long term loan.

There are calculators online but make sure you are familiar because I get a lot of people call me because their loan officer failed to run the numbers and they are getting ready to lose a deal or earnest money.If you want to go FHA you can always put more down but I would take a look at Fannie Mae as well for High Balance areas.  

Currently only 335k left on the loan but the property at the time of refinancing appraised for about 550k.Are there any options for them to utilize equity maybe or some type of loan program that would put a lien on the property to get the issue fixed?

The key evaluation data points for STR investors are accurate records of rental income and occupancy and/or projections from local mangers and online tools.
