You can try PenFed -- they had halted lending on investments until 2024 so they may be lending on investments now. https://www.penfed.org/You can also do a cash out refinance.

Electric heat is outrageous and no one would install it.

I just wire in the money and sit back to enjoy the cash flow, appreciation, and tax benefits.

I am currently looking at buying a new construction home as a long term rental property. sales price $214000. first my lender told me I can do 0 down. and I am really excited about this deal. but later he told me that am not qualified for 0 down because of my income. the other option is that I can do fha with 3.5% down, 6.125% interest rate. cash to close is $14000. my monthly payment is around $1575-$1590.it can at least rent for $1700 as a long term rental property.

You have props, cash , crews ?  

I currently pay the water and internet bill out of pocket and only request rent and the electric bill be paid for by the tenants.

That said, we’re currently cash poor.

Additionally, there are pockets where long-term rental returns are also amazing and can cash flow great, you just need to know where to invest.  

My plan will be to purchase a vacant land with cash and finance the home build through a private money loan.

I wouldn't buy any short-term rental without doing that analysis in the first place, especially if it's overseas.If you buy a property in Mexico and pay cash for it, it's gonna be hard not to turn a profit when renting short-term given how low the costs are.
