This could be an alternative method you use if you have trouble getting a HELOC on your property that a lot of investors who use the BRRRR method use.

You can also pay a trusted person using westeren union etc using credit card and then ask them to  deposit in your bank accounthttps://www.bankrate.com/finance/credit-cards/how-to-send-mo...Lower-cost alternatives for sending money with a credit cardMany issuers are introducing new ways for cardmembers to tap into their credit line to send money to friends and family.

I'm simply offering an alternative viewpoint based on the current market conditions and the heightened competition.It's easy to tell people to put sticky notes on someone's door, but what is the true cost and benefit? 

The alternative would be to buy a lot and build a new 4,500 sq ft home.

Roma in Mexico City is an awesome area for lifestyle but there's but STRs are going to be regulated there and possibly banned and LTRs are not a profitable alternative.

I'd try setup an alternative for her. 

I've been an investor and broker for the last 10 years in FL and NC, and specialize in the mountain regions, and beach regions because that's where most of the tourists, and investors who want getaways, invest (certainly there are many other interesting markets to invest however, booming wine country for example..)To add to it, I love the environmentally responsible home building, that's something I've had an interest in for a while, and I've worked with several contractors and architects in the last few years to come up with a useful plan for alternative and environmentally responsible building materials. 

I suppose if your numbers aren't working, you certainly have to look for alternatives.

What I mean by that is you need to have alternate properties you own support other properties you own.
