I just sold a spec, I built a house for my self last year and finished a spec this year, I bough the lots at tax sale, and I was the GC, HVAC, Tile, Flooring, Cabinet, Painter, and Misc. guy, made a nice profit, but the crappy part is taxes, its like a flip, short term gains. good luck!

I’m assuming it’s just like everything else, won’t learn it (or potentially get any sort of leads) until you do get it.

Some common names you'll see thrown around a lot: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend you search for each of those apps online and see what they offer, how much they charge, etc.

Remember that if you put your name and doing the flip something happens, you are directly liable to whatever happen.Make sure to protect yourself and your partner in such situations.

Biggest suggestion would be to make sure you are flexible, willing to work with multiple housing programs, and hire a good manager if you are not going to self manage the units.

I am now planning to do wholesaling with any leads that I get that I cannot buy myself. 

If you were to prioritize the following list from most important to least in any given time period:
Mortgage ratesCount of Properties for SaleAverage Property Sale PriceAverage Property List PriceAverage Sale to List...

I self managed my 401K from 2000 to 2016 when I retired averaging 12% every year for 16 years.

Best part is, my money continues to grow even while I have a loan out due to something called a non-direct recognition loan.

For instance, direct mailing.
