In my opinion, who cares how many unqualified tenants are attracted if I am able to attract a good qualified tenant readily.

3) what’s the plan if they spend that $3,500 and a month later another $2,000 bill comes up?

If you are planning on buying a turnkey property anyway, I suppose it could provide some insight into the locations they are working in and as I said above, if you did buy a property through them...the academy fee is refunded.Definitely don't take my word for it but it's helped me so far. 

Construction loans don't care about the properties income (DSCR loans do) but construction loans do care about you making the payments while the home is under construction and then REFINANCING out of the construction loan after the construction is complete. 

After that I plan to quit my job and become a full time investor flipping properties.

I plan to save the rental income for reserves, screen tenants properly, buy in C+ to B class properties. 

The numbers and business plan more than adequately support the project numbers (can share privately). 

However, if you need fast access to funds or have difficulty qualifying for a HELOC, a hard money loan could be a viable alternative, especially if you have a clear plan to refinance quickly.

Managing the $34,000 renovation budget required careful oversight to ensure timely completion.

I use Follow Up Boss and just have each lead tagged differently with different action plans
