I have to try something that would allow me to make money online because my currency is $7 to $1 US and the key a lot of the time is speed.

Most information on line concerning wholesaling is BIASED because the person providing the information is benefiting in some way by the distortion of facts6.

Check out other online guides available here: https://www.biggerpockets.com/guides3.

Your idea of purchasing and then refinancing with a heloc is perfectly fine. 

Refinancing a hard money loan to another hard money loan is not easy and may require the borrower bringing cash to the table if the ARV does not support the rehab budget and loan payoff amount.

Makes it easy for the Realtors, but stopped me from viewing the house more online. 

On top of the fact that values and rents rise during the time you own the property.....refinancing, or snowballing payments can bring your payments down on top of it.  

Lease Management - Avail.co, Apartments.com, Buildium, TenantCloud,  - many others - they can List For Rent, Schedule Showings, Provide Applications, Screen Tenants, Setup Leases, Setup and Manage Rent Payment, and other things (keep track of maintenance, keep track of expenses and make reports for accountants etc) Tenants like it because its online and makes it clear what they need to do - This also helps answer Drews question to you. - Showing a property - I have less to say on this one, looking for ideas myself.

If I like them and they meet the criteria I ask them to apply online.

Yes, there are a lot of people who spend less than they make and have a surplus.There are others who are inheriting wealth from othersBut there is another subset that we often forget: those who have equity in their homes.Much of the equity has built up due to a runup in home values since 2020, which allows these people to use a HELOC to purchase a home for cash.When rates were low there was a group of people who were using Hard money to purchase and rehab buildings and then refinancing at the end this was the BRRR strategy.Hard Money is not an option these days since the cost of refinancing at the end of the project is too expensive.So when we see people paying cash, it is often pent-up savings and HELOC money that people use, and not as often Hard Money.
