Using simple numbers, assume I want to purchase a $100,000 property using crypto as collateral:- I pay the closing costs with cash- I put down 10% down payment with cash ($10,000) - I utilize a crypto mortgage for the remaining 90% ($90,000) This way, I still keep my crypto and I have a property, both of which may accrue in value over the long-term.

I recently made an offer on a duplex, it's 4bed 3bath front unit + 2bed 2bath rear unitcurrently rear unit is rented for below market price at $930, market is around $1100-1200, rear unit is in very good condition and tenant maintained it well and i plan to keep her.

When you consider a HELOC, keep in mind that you need to apply and qualify for that as well.

You don't really have a lot of multifamily around there but I would really keep an eye out for that and if something that make sense pops up around there I would go for it. 

My partner and I wouldn't touch that $50k, and they keep 100% of that, however after our investment, we then get a percentage of everything they get starting at $50,001..

Keep learning and refining your approach, and you'll increase your chances of successful BRRRR deals. 

I don't think most tenants would do a good job of keeping the door clean.

When you get to the rear car do you keep running so you can try to get to the front car?

I don't know which city you're thinking about buying in, but if it is a growing and appreciating market it's worth keeping in mind that home-values/rents will most likely go up over time.

what's your personal guideline for how much to keep in reserves per property?
