The price point for a positive cash flowing single family house rental is typically 120-180k purchase price here so I am sure you'll be able to scale very quickly here with the capital you're working with.

congratulations on your house hack!

I'd also send it registered mail or deliver it to the house yourself. 

I love investing and developing myself, but I do not have enough experience, and this is what makes me hesitant to enter this field.So I want to ask you, what are the ways that will make me start investing in real estate or long-term housing?

I saw once where a developer gave the buyer a pass on paying HOA fees till a house was built on a lot. 

you borrow on your house lend to another and they default your now are fubared.

EBR housing allows around $1,300/month for 3 bedrooms.

I have a lender that will do cash out refinances even if no rehab was done on the property, using the higher appraised value the day after you buy a house.

Try to setup an appointment with them.Ask the top agents in your office if you could hold open houses for them. 

2 years to build a house is crazy.
