@Joseph Turner, if you're looking to buy in CA areas with high levels of appreciation, I've had clients take out a HELOC or 2nd mortgage and pay back the HELOC or 2nd with a cash out refinance once values appreciate. 

I am interested in recommendations for online courses or books (or other sources of information) that people have found useful. 

The property is in my name, and I am paying the mortgage.

Doing research online, it seems the price of an ADU might be around 350k8.

This bridge loan will position our client (who is very experienced and seasoned in this market) to successfully continue lease up and manage rent increases up to market until the property is primed for the HUD take out.If you are experiencing a similar story with any of your multifamily assets, please don’t hesitate to reach out directly, and we will work to identify if there is a solution to revitalizing your deal with perhaps a new Bridge loan until it is fully stabilized for agency or HUD.Maureese Jones | Commercial Mortgage BrokerCell: 717-881-3358 | Website: gparency.comAddress: 481 Oak Glen Rd, Howell Township, NJ 07731Follow me on LinkedIn

Purchased house for $260k at 3.8% 30-yr fixedCurrent mortgage payment is around $1850.

Just stick to the basics and don't sucked into all the online fitness crap you see every day.   

There is a mortgage of 280k on the property in question with a current market value 500k.  

I have not seen an online tool that is accurate across the board.
