You could offer to do month by month to see how it goes for a set period of time (eg 3 months) and then if it goes well and she's comfortable with her expenses, to do a lease at that point.

You get what you put in, period.

I will be able to turn profit within the first 3 month after the delivery and setup period which could be anywhere from 3/4months.

Some items considering:- Chichen Itza- Swimming in cenote Ik Kil- Valladolid Centro- Las Coloradas- Izamal- Akumal beach- Shopping in Playa del Carmen- Tulum Ruins- Cenote Dos Ojos- Xplor- Parque Nacional de los Arrecifes (cozumel island)Have not yet looked into transportation or lodging for period outside the conference dates.  

Do I stand a chance in small claims to file for one day they refused to pay, legal charges and my wages lost from work because tenants unitarily extended their contract by one day without asking. 

Construction can have unforseen costs, construction loans for rounds of funding can be more expensive over time, rent markets can drop, vacancies in market can increase.Typically entitlement phase of land most risk, followed by development, followed by vacant building turn around, followed by half vacant building, followed by mainly full building with value add component, followed by brand new building with market or below in place rents and everything new with good location.Along that spectrum of course you go from heavy equity upside potential to mainly just the cash flow return and hopefully price appreciation over time.Investors have to decide on the spectrum of their risk assessment to capital over what period of time how they will allocate between all one type of investment or multiple and what percentages.

For sms i send out messages to people who have opted into my website over a 6 month period and its worked well 

I can definitely help you find refinance solutions that fit your strategy, including options with shorter seasoning periods and up to 75% LTV cash-out refinances.I have relationships with dozens of private lenders who cater specifically to foreign investors, all of which offer flexible terms that could align with your goals.

Searching to see if any lenders are doing a cash-out with no seasoning period. 

@Ben Magee, In my state (PA) a tenant may break a lease WITH NO PENALTY if a unit is uninhabitable for an extended period and the landlord has been unable/unwilling to correct it.
