My current goal is to build a close team that I can count on, that can count on me, and to own 4 long term rentals in the next 4 years. 

If your brother doesn't help with co-signing, I would suggest purchasing your own property.

Guess what, people still prefer unattached single family homes on their own fenced lot.  

My question is, should I wait until end of next year to invest, assuming capital and all is aligned by early 2025, or invest in property while simultaneously paying my own rent elsewhere?

Once the renovation was complete, I started searching for a property management company, as I don’t manage my own properties.

@Jonathan Heacock if you go with a wholesaler, understand that they will only expose your property to whoever they have on their distribution list.So, recommend only giving them max of 30 days to sell it.

I'd recommend adding a consultation fee but seems like your trying to deceive your father.  

That way, you’ll have control over the operation and might be able to squeeze in a few extra bookings to pad your numbers.

I am not sure I can 100% answer your question. 

@John Anderson definitelyjust make sure the HOA allows investors purchase and rent from day 1.based on your budget, I know of another HOA in DFW that is allowing new builds for investors.
