Their CPA can help them with a basic cost seg on that.But for larger complexes, yes, it definitely makes sense to pay a cost seg engineering firm for their services as it can result in significant tax savings.

My husband and I can see ourselves using our house here as a base for more adventures in Mexico and beyond.

I could have added a basement and another 1000 sq. ft. of living space to add more equity. 

Got a base hit under contract!

Well lots of the purchase cost is based on the purchase price which BP does not allow you to give until the end.I love the BP Calculator as a base and using it motivated me to create my own so my statements above are not meant to crap on the BP products but I'm stating things I was struggling with when running numbers or when I was asked to provide more detailed numbers from lenders.

Since you have to do at least a basic title search before bidding on a foreclosure you can pick up the date and the amount of the original note.

There is a basement that has a garage in it.

In doing this I was able to purchase a great starter property within 3 months of this mindset change by doing the following:1) Connecting with a local agent/investor who was able to set me up with an MLS search that could fuel properties to be analyze with BP calculators.2) Working with local mortgage brokers to understand FHA owner occupant loans which combined with a state funded new-buyer assistance program (and negotiated seller paid closing costs) allowed me to close with only $2,000 out of pocket.3) Ultimately close on a base-hit property with virtually no money out of pocket, source my first tenants, do some basic cosmetic work to boost rents, and gain a TON of relatively low risk knowledge that will better set my up for future BRRRR investing.Although BRRRR is an amazing strategy, I highly recommend exploring house hacking in order to hit the ground running and get some experience under your belt.

I would say a basement ADU should add $150k range of equity in Ravenswood so definitely worth it + the cashflow.

But a SLAB foundation.. whats your thoughts on that vs a basement / Crawlspace setup for a duplex rental?
